- # Welcome to the Neovim Tutorial
- Neovim is a very powerful editor that has many commands, too many to explain in
- a tutorial such as this. This tutorial is designed to describe enough of the
- commands that you will be able to easily use Neovim as an all-purpose editor.
- It is IMPORTANT to remember that this tutorial is set up to teach by use. That
- means that you need to do the exercises to learn them properly. If you only
- read the text, you will soon forget what is most important!
- For now, make sure that your Caps-Lock is off and press the `j`{normal} key enough
- times to move the cursor so that Lesson 0 completely fills the screen.
- # Lesson 0
- NOTE: The commands in the lessons will modify the text, but those changes
- won't be saved. Don't worry about messing things up; just remember that
- pressing [<Esc>](<Esc>) and then [u](u) will undo the latest change.
- This tutorial is interactive, and there are a few things you should know.
- - Type [<Enter>](<Enter>) on links [like this](holy-grail ) to open the linked help section.
- - Or simply type [K](K) on any word to find its documentation!
- - You can close this help window with `:q`{vim}
- - Sometimes you will be required to modify text like
- this here
- Once you have done the changes correctly, the ✗ sign at the left will change
- to ✓. I imagine you can already see how neat Neovim can be.
- Other times, you'll be prompted to run a command (I'll explain this later):
- ~~~ cmd
- :help <Enter>
- ~~~
- or press a sequence of keys
- ~~~ normal
- <Esc>0f<Space>d3wP$P
- ~~~
- Text within <'s and >'s (like `<Enter>`{normal}) describes a key to press
- instead of text to type.
- Now, move to the next lesson (use the `j`{normal} key to scroll down).
- ## Lesson 1.1: MOVING THE CURSOR
- ** To move the cursor, press the `h`, `j`, `k`, `l` keys as indicated. **
- ↑
- k Hint: The `h`{normal} key is at the left and moves left.
- ← h l → The `l`{normal} key is at the right and moves right.
- j The `j`{normal} key looks like a down arrow.
- ↓
- 1. Move the cursor around the screen until you are comfortable.
- 2. Hold down the down key (`j`{normal}) until it repeats.
- Now you know how to move to the next lesson.
- 3. Using the down key, move to Lesson 1.2.
- NOTE: If you are ever unsure about something you typed, press <Esc> to place
- you in Normal mode. Then retype the command you wanted.
- NOTE: The cursor keys should also work. But using hjkl you will be able to
- move around much faster, once you get used to it.
- # Lesson 1.2: EXITING NEOVIM
- !! NOTE: Before executing any of the steps below, read the entire lesson !!
- 1. Press the <Esc> key (to make sure you are in Normal mode).

- This quits the editor, DISCARDING any changes you have made.
- 3. Open Neovim and get back here by executing the command that got you into
- this tutorial. That might be:
- :Tutor <Enter>
- 4. If you have these steps memorized and are confident, execute steps
- 1 through 3 to exit and re-enter the editor.
- NOTE: [:q!](:q) <Enter> discards any changes you made. In a few lessons you
- will learn how to save the changes to a file.
- 5. Move the cursor down to Lesson 1.3.
- ## Lesson 1.3: TEXT EDITING - DELETION
- ** Press `x`{normal} to delete the character under the cursor. **

- 4. Repeat steps 2 through 4 until the sentence is correct.
- The ccow jumpedd ovverr thhe mooon.
- 5. Now that the line is correct, go on to Lesson 1.4.
- NOTE: As you go through this tutorial, do not try to memorize everything,
- your Neovim vocabulary will expand with usage. Consider returning to
- this tutorial periodically for a refresher.
- # Lesson 1.4: TEXT EDITING: INSERTION
- ** Press `i`{normal} to insert text. **
- 1. Move the cursor to the first line below marked ✗.
- 2. To make the first line the same as the second, move the cursor on top
- of the first character AFTER where the text is to be inserted.
- 3. Press `i`{normal} and type in the necessary additions.
- 4. As each error is fixed press `<Esc>`{normal} to return to Normal mode.
- Repeat steps 2 through 4 to correct the sentence.
- There is text misng this .
- There is some text missing from this line.
- 5. When you are comfortable inserting text move to Lesson 1.5.
- # Lesson 1.5: TEXT EDITING: APPENDING
- ** Press `A`{normal} to append text. **
- 1. Move the cursor to the first line below marked ✗.
- It does not matter on what character the cursor is in that line.
- 2. Press [A](A) and type in the necessary additions.
- 3. As the text has been appended press `<Esc>`{normal} to return to Normal
- mode.
- 4. Move the cursor to the second line marked ✗ and repeat
- steps 2 and 3 to correct this sentence.
- There is some text missing from th
- There is some text missing from this line.
- There is also some text miss
- There is also some text missing here.
- 5. When you are comfortable appending text move to Lesson 1.6.
- # Lesson 1.6: EDITING A FILE
- ** Use `:wq`{vim} to write a file and quit. **
- !! NOTE: Before executing any of the steps below, read the entire lesson !!
- 1. Exit this tutorial as you did in Lesson 1.2: `:q!`{vim}
- Or, if you have access to another terminal, do the following there.
- 2. At the shell prompt type this command:
- ~~~ sh
- $ nvim tutor
- ~~~
- 'nvim' is the command to start the Nvim editor, 'tutor' is the name of
- the file you wish to edit. Use a file that may be changed.
- 3. Insert and delete text as you learned in the previous lessons.
- 4. Save the file with changes and exit Neovim with:
- ~~~ cmd
- :wq
- ~~~
- Note you'll need to press `<Enter>` to execute the command.
- 5. If you have quit this tutorial in step 1, restart and move down
- to the following summary.
- 6. After reading and understanding the above steps: do them.
- # Lesson 1 SUMMARY
- 1. The cursor is moved using either the arrow keys or the hjkl keys.
- h (left) j (down) k (up) l (right)

- 5. To insert or append text type:
- `i`{normal} insert text `<Esc>`{normal} insert before the cursor.
- `A`{normal} append text `<Esc>`{normal} append after the line.
- NOTE: Pressing `<Esc>`{normal} will place you in Normal mode or will cancel
- an unwanted and partially completed command.
- Now continue with Lesson 2.
- # Lesson 2.1: DELETION COMMANDS
- ** Type `dw`{normal} to delete a word. **
- 1. Press `<Esc>`{normal} to make sure you are in Normal mode.
- 2. Move the cursor to the line below marked ✗.
- 3. Move the cursor to the beginning of a word that needs to be deleted.
- 4. Type [d](d)[w](w) to make the word disappear.
- There are a some words fun that don't belong paper in this sentence.

- 1. Press `<Esc>`{normal} to make sure you are in Normal mode.
- 2. Move the cursor to the line below marked ✗.
- 3. Move the cursor to the end of the correct line (AFTER the first . ).
- 4. Type `d$`{normal} to delete to the end of the line.
- Somebody typed the end of this line twice. end of this line twice.
- 5. Move on to Lesson 2.3 to understand what is happening.
- # Lesson 2.3: ON OPERATORS AND MOTIONS
- Many commands that change text are made from an [operator](operator) and a [motion](navigation).
- The format for a delete command with the [d](d) delete operator is as follows:
- d motion
- Where:
- d - is the delete operator.
- motion - is what the operator will operate on (listed below).
- A short list of motions:
- [w](w) - until the start of the next word, EXCLUDING its first character.
- [e](e) - to the end of the current word, INCLUDING the last character.
- [$]($) - to the end of the line, INCLUDING the last character.
- Thus typing `de`{normal} will delete from the cursor to the end of the word.
- NOTE: Pressing just the motion while in Normal mode without an operator
- will move the cursor as specified.
- # Lesson 2.4: USING A COUNT FOR A MOTION
- ** Typing a number before a motion repeats it that many times. **
- 1. Move the cursor to the start of the line marked ✓ below.
- 2. Type `2w`{normal} to move the cursor two words forward.
- 3. Type `3e`{normal} to move the cursor to the end of the third word forward.
- 4. Type `0`{normal} ([zero](0)) to move to the start of the line.
- 5. Repeat steps 2 and 3 with different numbers.
- This is just a line with words you can move around in.
- 6. Move on to Lesson 2.5.
- # Lesson 2.5: USING A COUNT TO DELETE MORE
- ** Typing a number with an operator repeats it that many times. **
- In the combination of the delete operator and a motion mentioned above you
- insert a count before the motion to delete more:
- d number motion
- 1. Move the cursor to the first UPPER CASE word in the line marked ✗.
- 2. Type `d2w`{normal} to delete the two UPPER CASE words
- 3. Repeat steps 1 and 2 with a different count to delete the consecutive
- UPPER CASE words with one command
- This ABC DE line FGHI JK LMN OP of words is Q RS TUV cleaned up.
- # Lesson 2.6: OPERATING ON LINES
- ** Type `dd`{normal} to delete a whole line. **
- Due to the frequency of whole line deletion, the designers of Vi decided
- it would be easier to simply type two d's to delete a line.
- 1. Move the cursor to the second line in the phrase below.
- 2. Type [dd](dd) to delete the line.
- 3. Now move to the fourth line.
- 4. Type `2dd`{normal} to delete two lines.
- 1) Roses are red,
- 2) Mud is fun,
- 3) Violets are blue,
- 4) I have a car,
- 5) Clocks tell time,
- 6) Sugar is sweet
- 7) And so are you.
- # Lesson 2.7: THE UNDO COMMAND
- ** Press `u`{normal} to undo the last commands, `U`{normal} to fix a whole line. **
- 1. Move the cursor to the line below marked ✗ and place it on the first error.
- 2. Type `x`{normal} to delete the first unwanted character.
- 3. Now type `u`{normal} to undo the last command executed.
- 4. This time fix all the errors on the line using the `x`{normal} command.
- 5. Now type a capital `U`{normal} to return the line to its original state.
- 6. Now type `u`{normal} a few times to undo the `U`{normal} and preceding commands.
- 7. Now type `<C-r>`{normal} (Control + R) a few times to redo the commands.
- Fiix the errors oon thhis line and reeplace them witth undo.
- 8. These are very useful commands. Now move on to the Lesson 2 Summary.
- # Lesson 2 SUMMARY
- 1. To delete from the cursor up to the next word type: `dw`{normal}
- 2. To delete from the cursor to the end of a line type: `d$`{normal}
- 3. To delete a whole line type: `dd`{normal}
- 4. To repeat a motion prepend it with a number: `2w`{normal}
- 5. The format for a change command is:
- operator [number] motion
- where:
- operator - is what to do, such as [d](d) for delete
- [number] - is an optional count to repeat the motion
- motion - moves over the text to operate on, such as:
- [w](w) (word),
- [$]($) (to the end of line), etc.
- 6. To move to the start of the line use a zero: [0](0)
- 7. To undo previous actions, type: `u`{normal} (lowercase u)
- To undo all the changes on a line, type: `U`{normal} (capital U)
- To undo the undo's, type: `<C-r>`{normal}

- b) Violets are blue,
- c) Intelligence is learned,
- a) Roses are red,
- NOTE: You can also put the text before the cursor with `P`{normal} (capital P)
- # Lesson 3.2: THE REPLACE COMMAND
- ** Type `rx`{normal} to replace the character at the cursor with x. **
- 1. Move the cursor to the first line below marked ✗.
- 2. Move the cursor so that it is on top of the first error.
- 3. Type `r`{normal} and then the character which should be there.
- 4. Repeat steps 2 and 3 until the first line is equal to the second one.
- Whan this lime was tuoed in, someone presswd some wrojg keys!
- When this line was typed in, someone pressed some wrong keys!
- 5. Now move on to Lesson 3.3.
- NOTE: Remember that you should be learning by doing, not memorizing.
- # Lesson 3.3: THE CHANGE OPERATOR
- ** To change until the end of a word, type `ce`{normal}. **
- 1. Move the cursor to the first line below marked ✗.
- 2. Place the cursor on the "u" in "lubw".
- 3. Type `ce`{normal} and the correct word (in this case, type "ine" ).

- This lubw has a few wptfd that mrrf changing usf the change operator.
- This line has a few words that need changing using the change operator.
- Notice that [c](c)e deletes the word and places you in Insert mode.
- # Lesson 3.4: MORE CHANGES USING `c`{normal}
- ** The change operator is used with the same motions as delete. **
- 1. The change operator works in the same way as delete. The format is:
- c [number] motion
- 2. The motions are the same, such as `w`{normal} (word) and `$`{normal} (end of line).
- 3. Move to the first line below marked ✗.
- 4. Move the cursor to the first error.
- 5. Type `c$`{normal} and type the rest of the line like the second and press `<Esc>`{normal}.
- The end of this line needs some help to make it like the second.
- The end of this line needs to be corrected using the `c$`{normal} command.
- NOTE: You can use the Backspace key to correct mistakes while typing.
- # Lesson 3 SUMMARY
- 1. To put back text that has just been deleted, type [p](p). This puts the
- deleted text AFTER the cursor (if a line was deleted it will go on the
- line below the cursor).
- 2. To replace the character under the cursor, type [r](r) and then the
- character you want to have there.
- 3. The [change operator](c) allows you to change from the cursor to where
- the motion takes you. Type `ce`{normal} to change from the cursor to the

- 4. The format for change is:
- c [number] motion
- Now go on to the next lesson.
- # Lesson 4.1: CURSOR LOCATION AND FILE STATUS
- ** Type `<C-g>`{normal} to show your location in a file and the file status.
- Type `G`{normal} to move to a line in the file. **
- NOTE: Read the entire lesson before executing any of these steps!!
- 1. Hold down the `<Ctrl>`{normal} key and press `g`{normal}. We call this `<C-g>`{normal}.
- A message will appear at the bottom of the page with the filename and
- the position in the file. Remember the line number for Step 3.
- NOTE: You may see the cursor position in the lower right corner of the
- screen. This happens when the ['ruler']('ruler') option is set.
- 2. Press [G](G) to move you to the bottom of the file.
- Type [gg](gg) to move you to the start of the file.
- 3. Type the number of the line you were on and then `G`{normal}. This will
- return you to the line you were on when you first pressed `<C-g>`{normal}.
- 4. If you feel confident to do this, execute steps 1 through 3.
- # Lesson 4.2: THE SEARCH COMMAND
- ** Type `/`{normal} followed by a phrase to search for the phrase. **
- 1. In Normal mode type the `/`{normal} character. Notice that it and the

- 2. Now type 'errroor' `<Enter>`{normal}. This is the word you want to search for.
- 3. To search for the same phrase again, simply type [n](n).
- To search for the same phrase in the opposite direction, type [N](N).
- 4. To search for a phrase in the backward direction, use [?](?) instead of `/`{normal}.
- 5. To go back to where you came from press `<C-o>`{normal}.
- (keep `<Ctrl>`{normal} pressed down while pressing the letter `o`{normal}).
- Repeat to go back further. `<C-i>`{normal} goes forward.
- "errroor" is not the way to spell error; errroor is an error.
- NOTE: When the search reaches the end of the file it will continue at the
- start, unless the ['wrapscan']('wrapscan') option has been reset.
- # Lesson 4.3: MATCHING PARENTHESES SEARCH
- ** Type `%`{normal} to find a matching ),], or }. **
- 1. Place the cursor on any (, [, or { in the line below marked ✓.
- 2. Now type the [%](%) character.
- 3. The cursor will move to the matching parenthesis or bracket.
- 4. Type `%`{normal} to move the cursor to the other matching bracket.
- 5. Move the cursor to another (,),[,],{ or } and see what `%`{normal} does.
- This ( is a test line with ('s, ['s ] and {'s } in it. ))
- NOTE: This is very useful in debugging a program with unmatched parentheses!
- # Lesson 4.4: THE SUBSTITUTE COMMAND
- ** Type `:s/old/new/g` to substitute "new" for "old". **
- 1. Move the cursor to the line below marked ✗.
- 2. Type
- ~~~ cmd
- :s/thee/the/
- ~~~
- NOTE: the [:s](:s) command only changed the first match of "thee" in the line.
- 3. Now type
- ~~~ cmd
- :s/thee/the/g
- ~~~
- Adding the g [flag](:s_flags) means to substitute globally in the line,
- change all occurrences of "thee" in the line.
- Usually thee best time to see thee flowers is in thee spring.
- 4. To change every occurrence of a character string between two lines, type
- ~~~ cmd
- :#,#s/old/new/g
- ~~~
- where # are the line numbers of the range of lines where the
- substitution is to be done (i.e., `1,3` means from line 1 to line 3, inclusive).
- Type
- ~~~ cmd
- :%s/old/new/g
- ~~~
- to change every occurrence in the whole file.
- Type
- ~~~ cmd
- :%s/old/new/gc
- ~~~
- to find every occurrence in the whole file, with a prompt whether to
- substitute or not.
- NOTE: You can also select the lines you want to substitute first using visual-mode.
- This will be explained more in a future lesson.
- # Lesson 4 SUMMARY
- 1. `<C-g>`{normal} displays your location and the file status.
- `G`{normal} moves to the end of the file.
- number `G`{normal} moves to that line number.
- `gg`{normal} moves to the first line.
- 2. Typing `/`{normal} followed by a phrase searches FORWARD for the phrase.
- Typing `?`{normal} followed by a phrase searches BACKWARD for the phrase.
- After a search type `n`{normal} to find the next occurrence in the same
- direction or `N`{normal} to search in the opposite direction.
- `<C-o>`{normal} takes you back to older positions, `<C-i>`{normal} to
- newer positions.
- 3. Typing `%`{normal} while the cursor is on a (,),[,],{, or } goes to its
- match.
- 4. To substitute new for the first old in a line type
- ~~~ cmd
- :s/old/new
- ~~~
- To substitute new for all 'old's on a line type
- ~~~ cmd
- :s/old/new/g
- ~~~
- To substitute phrases between two line #'s type
- ~~~ cmd
- :#,#s/old/new/g
- ~~~
- To substitute all occurrences in the file type
- ~~~ cmd
- :%s/old/new/g
- ~~~
- To ask for confirmation each time add 'c'
- ~~~ cmd
- :%s/old/new/gc
- ~~~
- # Lesson 5.1: HOW TO EXECUTE AN EXTERNAL COMMAND
- ** Type `:!`{vim} followed by an external command to execute that command. **
- 1. Type the familiar command `:`{normal} to set the cursor at the bottom of
- the screen. This allows you to enter a command-line command.
- 2. Now type the [!](!cmd) (exclamation point) character. This allows you to
- execute any external shell command.
- 3. As an example type "ls" following the "!" and then hit `<Enter>`{normal}.
- This will show you a listing of your directory, just as if you were
- at the shell prompt.
- NOTE: It is possible to execute any external command this way, and you
- can include arguments.
- NOTE: All `:`{vim} commands are executed when you press `<Enter>`{normal}.
- # Lesson 5.2: MORE ON WRITING FILES
- ** To save the changes made to the text, type `:w`{vim} FILENAME. **
- 1. Type `:!ls`{vim} to get a listing of your directory.
- You already know you must hit `<Enter>`{normal} after this.
- 2. Choose a filename that does not exist yet, such as TEST.
- 3. Now type:
- ~~~ cmd
- :w TEST
- ~~~
- (where TEST is the filename you chose.)
- 4. This saves the current file under the name TEST.
- To verify this, type `:!ls`{vim} again to see your directory.
- NOTE: If you were to exit Neovim and start it again with `nvim TEST`, the file
- would be an exact copy of the tutorial when you saved it.
- 5. Now remove the file by typing:
- ~~~ cmd
- :!rm TEST
- ~~~
- # Lesson 5.3: SELECTING TEXT TO WRITE
- ** To save part of the file, type `v`{normal} motion `:w FILENAME`{vim}. **
- 1. Move the cursor to this line.
- 2. Press [v](v) and move the cursor to the fifth item below. Notice that the
- text is highlighted.
- 3. Press the `:`{normal} character. At the bottom of the screen
- `:'<,'>`{vim}
- will appear.
- 4. Type
- `:w TEST`{vim}
- where TEST is a filename that does not exist yet. Verify that you see
- `:'<,'>w TEST`{vim}
- before you press `<Enter>`{normal}.
- 5. Neovim will write the selected lines to the file TEST. Use `:!ls`{vim} to see it.
- Do not remove it yet! We will use it in the next lesson.
- NOTE: Pressing [v](v) starts [Visual selection](visual-mode). You can move the cursor around to
- make the selection bigger or smaller. Then you can use an operator to
- do something with the text. For example, `d`{normal} deletes the text.
- # Lesson 5.4: RETRIEVING AND MERGING FILES
- ** To retrieve the contents of a file, type `:r FILENAME`{vim}. **
- 1. Place the cursor just above this line.
- NOTE: After executing Step 2 you will see text from Lesson 5.3. Then move
- DOWN to see this lesson again.
- 2. Now retrieve your TEST file using the command
- `:r TEST`{vim}
- where TEST is the name of the file you used.
- The file you retrieve is placed below the cursor line.
- 3. To verify that a file was retrieved, cursor back and notice that there
- are now two copies of Lesson 5.3, the original and the retrieved version.
- NOTE: You can also read the output of an external command. For example,
- `:r !ls`{vim}
- reads the output of the `ls` command and puts it below the cursor.
- # Lesson 5 SUMMARY
- 1. [:!command](:!cmd) executes an external command.
- Some useful examples are:
- `:!ls`{vim} - shows a directory listing
- `:!rm FILENAME`{vim} - removes file FILENAME
- 2. [:w](:w) FILENAME writes the current Neovim file to disk with
- name FILENAME.
- 3. [v](v) motion :w FILENAME saves the Visually selected lines in file
- FILENAME.
- 4. [:r](:r) FILENAME retrieves disk file FILENAME and puts it
- below the cursor position.
- 5. [:r !dir](:r!) reads the output of the dir command and
- puts it below the cursor position.
- # Lesson 6.1: THE OPEN COMMAND
- ** Type `o`{normal} to open a line below the cursor and place you in Insert mode. **
- 1. Move the cursor to the line below marked ✓.
- 2. Type the lowercase letter `o`{normal} to [open](o) up a line BELOW the
- cursor and place you in Insert mode.
- 3. Now type some text and press `<Esc>`{normal} to exit Insert mode.
- After typing `o`{normal} the cursor is placed on the open line in Insert mode.
- 4. To open up a line ABOVE the cursor, simply type a [capital O](O), rather
- than a lowercase `o`{normal}. Try this on the line below.
- Open up a line above this by typing O while the cursor is on this line.
- # Lesson 6.2: THE APPEND COMMAND
- ** Type `a`{normal} to insert text AFTER the cursor. **
- 1. Move the cursor to the start of the line below marked ✗.
- 2. Press `e`{normal} until the cursor is on the end of "li".
- 3. Type the lowercase letter `a`{normal} to [append](a) text AFTER the cursor.
- 4. Complete the word like the line below it. Press `<Esc>`{normal} to exit Insert mode.
- 5. Use `e`{normal} to move to the next incomplete word and repeat steps 3 and 4.
- This li will allow you to pract appendi text to a line.
- This line will allow you to practice appending text to a line.
- NOTE: [a](a), [i](i) and [A](A) all go to the same Insert mode, the only
- difference is where the characters are inserted.
- # Lesson 6.3: ANOTHER WAY TO REPLACE
- ** Type a capital `R`{normal} to replace more than one character. **
- 1. Move the cursor to the first line below marked ✗. Move the cursor to
- the beginning of the first "xxx".
- 2. Now press `R`{normal} ([capital R](R)) and type the number below it in the
- second line, so that it replaces the "xxx".
- 3. Press `<Esc>`{normal} to leave [Replace mode](mode-replace). Notice that
- the rest of the line remains unmodified.
- 4. Repeat the steps to replace the remaining "xxx".
- Adding 123 to xxx gives you xxx.
- Adding 123 to 456 gives you 579.
- NOTE: Replace mode is like Insert mode, but every typed character
- replaces an existing character.
- # Lesson 6.4: COPY AND PASTE TEXT
- ** Use the `y`{normal} operator to copy text and `p`{normal} to put it. **
- 1. Go to the line marked with ✓ below and place the cursor after "a)".
- 2. Start Visual mode with `v`{normal} and move the cursor to just before
- "first".
- 3. Type `y`{normal} to [yank](yank) (copy) the highlighted text.
- 4. Move the cursor to the end of the next line: `j$`{normal}
- 5. Type `p`{normal} to [put](put) (paste) the text.
- 6. Press `a`{normal} and then type "second". Press `<Esc>`{normal} to leave
- Insert mode.
- 7. Use Visual mode to select "item.", yank it with `y`{normal}, move to the
- end of the next line with `j$`{normal} and put the text there with `p`{normal}
- a) This is the first item.
- b)
- NOTE: you can use `y`{normal} as an operator: `yw`{normal} yanks one word.
- NOTE: you can use `P`{normal} to put before the cursor, rather than after.
- # Lesson 6.5: SET OPTION
- ** Set an option so search and substitute commands ignore case. **
- There are many settings in Neovim that you can configure to suit your needs.
- 1. Search for 'ignore' by entering: `/ignore`
- Repeat several times by pressing `n`{normal}.
- 2. Set the 'ic' (Ignore case) option by entering:
- ~~~ cmd
- :set ic
- ~~~
- 3. Now search for 'ignore' again by pressing `n`{normal}.
- Notice that Ignore and IGNORE are now also found.
- 4. Set the 'hlsearch' and 'incsearch' options:
- ~~~ cmd
- :set hls is
- ~~~
- 5. Now type the search command again and see what happens: /ignore <Enter>
- 6. To disable ignoring case enter:
- ~~~ cmd
- :set noic
- ~~~
- 7. To invert the value of a setting, prepend it with "inv":
- ~~~ cmd
- :set invic
- ~~~
- NOTE: To remove the highlighting of matches enter:
- ~~~ cmd
- :nohlsearch
- ~~~
- NOTE: If you want to ignore case for just one search command, use [\c](/\c)
- in the phrase: /ignore\c <Enter>
- # Lesson 6 SUMMARY
- 1. Type `o`{normal} to open a line BELOW the cursor and start Insert mode.
- Type `O`{normal} to open a line ABOVE the cursor.
- 2. Type `a`{normal} to insert text AFTER the cursor.
- Type `A`{normal} to insert text after the end of the line.
- 3. The `e`{normal} command moves to the end of a word.
- 4. The `y`{normal} operator copies text, `p`{normal} pastes it.
- 5. Typing a capital `R`{normal} enters Replace mode until `<Esc>`{normal} is
- pressed.
- 6. Typing "[:set](:set) xxx" sets the option "xxx". Some options are:
- 'ic' 'ignorecase' ignore upper/lower case when searching
- 'is' 'incsearch' show partial matches for a search phrase
- 'hls' 'hlsearch' highlight all matching phrases
- You can either use the long or the short option name.
- 7. Prepend "no" to switch an option off:
- ~~~ cmd
- :set noic
- ~~~
- 8. Prepend "inv" to invert an option:
- ~~~ cmd
- :set invic
- ~~~
- # Lesson 7.1: GETTING HELP
- ** Use the online help system. **
- Neovim has a comprehensive online help system.
- To get started, try one of these three:
- - press the `<F1>`{normal} key (if you have one)
- - type `:help`{vim}
- Read the text in the help window to find out how the help works.
- Type `<C-w><C-w>`{normal} to jump from one window to another.
- Type `:q`{vim} to close the help window.
- You can find help on just about any subject, by giving an argument to the
- ":help" command. Try these (don't forget to press <Enter>):
- ~~~ cmd
- :help w
- :help c_CTRL-D
- :help insert-index
- :help user-manual
- ~~~
- # Lesson 7.2: CREATE A STARTUP SCRIPT
- ** Enable Neovim features. **
- Neovim is a very configurable editor. You can customise it any way you like.
- To start using more features create an "init.vim" file.
- 1. Start editing the "init.vim" file.
- `:call mkdir(stdpath('config'),'p')`{vim}
- `:exe 'edit' stdpath('config').'/init.vim'`{vim}
- 2. Write the file with:
- `:w`{vim}
- You can add all your preferred settings to this "init.vim" file.
- For more information type `:help init.vim`{vim}.
- # Lesson 7.3: COMPLETION
- ** Command line completion with `<C-d>`{normal} and `<Tab>`{normal}. **
- 1. List the contents of the current directory: `:!ls`{vim}
- 2. Type the start of a command: `:e`{vim}
- 3. Press `<C-d>`{normal} and Neovim will show a list of commands beginning with "e".
- 4. Press `<Tab>`{normal} and Neovim will complete the command name to ":edit".
- 5. Now add a space and the start of an existing file name: `:edit FIL`{vim}
- 6. Press `<Tab>`{normal}. Neovim will complete the name ("FIL" -> "FILE", if it is unique).
- NOTE: Completion works for many commands. It is especially useful for `:help`{vim}.
- # Lesson 7 SUMMARY
- 1. Type `:help`{vim}
- or press `<F1>`{normal} or `<Help>`{normal} to open a help window.
- 2. Type `:help TOPIC`{vim} to find help on TOPIC.
- 3. Type `<C-w><C-w>`{normal} to jump to another window
- 4. Type `:q`{vim} to close the help window
- 5. Create an init.vim startup script to keep your preferred settings.
- 6. While in command mode, press `<C-d>`{normal} to see possible completions.
- Press `<Tab>`{normal} to use one completion.
- # CONCLUSION
- This was intended to give a brief overview of the Neovim editor, just enough to
- allow you to use it fairly easily. It is far from complete as Neovim has
- many many more commands. Consult the help often.
- There are also countless great tutorials and videos to be found online.
