I’ve been learning to use neovim for almost 3 weeks now and it has been fun, coming from VSCode I guess I was spoiled by the feature rich IDE/text editor, however there is beauty in the simplicity keyboard oriented (Neo)vim text editor

I’ve been trying to get all the useful keyboard shortcuts and commands I’ve found in a single place and I though this could be helpful for other noobs like me, fosstodon community was helpful and shared their Tips n’ Tricks as well.

The Cheatsheet

This list is by no means a complete compendium but it is what I’ve found most useful and basic

• To enter NORMAL mode press Esc
• To enter INSERT mode type i (cursor position) or I (beginning of the current line)

From NORMAL mode:

• To enter VISUAL mode type v
• To enter VISUAL LINE mode type V
• To enter VISUAL BLOCK mode press Ctrl + v
• To append text type a (cursor position) or A (end of the current line)
• To navigate the document left, down, up and right press h, j, k, l respectively (or use the arrow keys)
• To go to the top and end of the document, type gg and G respectively
• To move to the beginning and end of the line type 0 and $ respectively
• To move forward or backward one word press w and b respectively
• To insert a line below or above the current line type o and O respectively
• To undo type u, to redo press Ctrl + r
• To repeat an action press .
• To move between last opened files press Ctrl + i (newer) Ctrl + o (older)
• To swap lines type ddp
• To swap two characters type xp
• To remove the current character type x
• To replace the current character type r<character>
• To correct a word (from the cursor position) type cw
• To correct a word (regardless of the cursor position) type ciw
• To scroll down the document so that only the last line is visible type Ctrl + f
• To search the document type /<search term>
• To go to next and previous tabs type gt and gT
• To switch between splits press Ctrl + w <movement keys> or Ctrl + w + w
• To start recording a macro press q<letter>, then execute actions/commands and pres q to stop recording
• To execute a macro type @<letter>, to execute the macro again type @@
• To enter COMMAND mode type :

From COMMAND mode:

• To close a file typeq
• To close a file discarding any changes type q!
• To close the text editor and all opened files type qa
• To save your changes to a file type w
• To save your changes and quit all open tabs wqa
• To read the help documentation about a topic type help <topic string>
• To read the help documentation about commands associated to a key type help <key>
• To open a new tab type tabnew <optional file>
• To switch between opened tabs type tabprevious and tabnext respectively
• To open a new horizontal split type split <optional file>
• To open a new vertical split type vsplit <optional file>
• To search and replace globally type %s/<regex or search term>/<replace term>/g<optional nc for confirmation>
• To “open a terminal” type term

From VISUAL LINE mode:

• To reflow text type gq

My current configuration

I thought that just for fun I’d share my init.vim (as of now, since I am still tweaking it) in case someone finds it useful:
