NOTES ON NEOVIM AND MY PERSONAL NEOVIM WORKFLOW

FOR OFFICIAL DOCUMENTATION OF NEOVIM, PLEASE VISIT THEIR GITHUB: https://github.com/neovim/neovim

ThePrimeagen: Command, Count, Motion

I have created this small txt file to document my basic neoneovim work flow
It is combined with notes about my espanso keybindings, which are meant to aid in the workflow
Keep in mind these are specific to my neovim setup and will definitely not work in all neovim setups

A FINAL NOTE: I recommend trying to coordinate your vim workflow throughout all of your applications. The easiest way to do this is to set up vim keybindings in your terminal:

In .bashrc:
set -o vi
In .zshrc:
bindkey -v

When setting up keybindings in say a tiling window manager like i3 or bspwm(my preferred twm), it may be a good idea to set up vim keybindings in that. Lastly, install vimium into your browser, as this will allow you to navigate your browser using vim keybindings (hjkldu for navigation, yy to grab the current url, / to search the page, etc.). Vimium is available in either chromium or firefox based browsers and is an essential part of my workflow along with Neovim.

-- Standard keybindings (all neovim)

NORMAL MODE

h - go one character left (prepend with a number to go that many characters)
j - go one character down (prepend with a number to go that many characters)
k - go one character up (prepend with a number to go that many characters)
l - go one character right (prepend with a number to go that many characters)
w - go to the right to the beginning of the next word (delimited by spaces)
b or shift b - go to the left to the beginning of the last word (delimited by spaces)
e or shift e - go to the right to the ending of the next word (delimited by spaces)
0 - go to beginning of line (prepend with a number to go that many characters)
_ - go the first character in the line
$ - go to the end of the line (prepend with a number to go that many characters)
gg - go to top of the page
shift + g - go to the bottom of the page
ctrl u -page up
ctrl d - page down
u - undoes last change (can be used with prepended numbers depending on how many steps you want to undo)
ctrl + r - reverts changes over after unintentional undoing (undoes the last undo commands, also can be prepended by a number)

/ - forwards slash searches for the word/term you wish to jump to, just press enter once it is highlighted
? - question mark searches for the word/term you wish to jump to, just press enter once it is highlighted
n - jump to the next occurence of search term entered from / or ? (/ goes forwards in document, ? goes backwards in document)
N - jump to the previous occurence of search term entered from / or ? (/ goes backwards in document, ? goes forwards in document)
* - search for all occurences of the word under current cursor


d - beginning d keybinding, can be combined with many of the above commands (it cuts, so you can paste it using p keybinding)
(can be prepended by a number, and multiples the amount of words/lines is deleted/cut)
dh - delete word one back (equivalent to db)
dj - delete one line down
dk - delete one line up
dl - delete word one forward (equivlanet to dw)
dd - delete current line
d0 - delete from current cursor position to the beginning of the line
d$ - delete from the current cursor position to the end of the line
dgg - delete from the current cursor position to the beginning of the document
dG - delete from the current position to the end of the document
dw - delete word on current position
de - delete current cursor position to the end of the word
db - delete current cursor position to the beginning of the word
x - delete character under current cursor position

c - c can be used instead of d, and will do pretty much the same thing, except it will go into INSERT mode after deletion

interesting use case:
di( - will delete everything encapsulated in the following parenthesis
di{ - will delete everything encapsulated in the following curly brackets
di[ - will delte everything encapsulated in the following square brackets
di" - will delte everything encapsulated in the following quotation marks

g - go
gg - go to top of document
shift + g - go to bottom of document
gf - go to file underneath cursor (html files are brought in using wget and
        rendered in editor)
gx - go to address and open with default BROWSER or FILE EXPLORER
gX - open file in file manager
gi - go to place in document where you last entered insert mode, and also enter insert mode (where did I leave off?)
gv - go to last selected text and enter visual mode
gn - go to the selection of your last search
gI insert text at the beginning of the line, no matter what the first characters
are
ga - print the hex code of the character under the cursor
gu - convert enter line to lowercase
gU - convert enter line to uppercase


y - beginning y keybinding, yanks or copies character or word for pasting elsewhere using the p keybinding
(can be prepended by a number, and multiples the amount of words/lines to be copied)
yh - copies one word back (equivalent to yb)
yj - copies one line down
yk - copies one line up
yl - copies one word forward (equivlanet to ye)
ye - copies one word forward
yb - copies one word back
yy - copies entire line
yw - copies entire word
y0 - copies from current cursor position to beginning of line
y$ - copies from current cursor position to end of line
yG - copies from current cursor position to the end of document
ygg - copies from current cursor position to the beginning of document

o - create line below and go into insert mode
shift + o - create line above and go into insert mod

f - go to the next instance of the next character (i.e. f+g will go to the next instance of 'g')
shift + f - same as f, but goes backwards (i.e. shift+f+g will go to the last instance of 'g')

t - same as f, but will go to one character before entered character
shift + t -same as shift + f, but goes backwards to one character before entered character

; - after f or t search of character, iterates over to the next instance of it in the line
, - after f or t search of character, iterates over to the last instance of it in the line

* - search forward the word currently under the cursor
# - search backward the word currently under the cursor

GOOD FOR USE WITHIN FUNCTION ENCAPSULATIONS
[{ - go to beginning encapsulation that begins with { ( can also be used with '(' )
]} - got o the ending encapsulation that ends with } ( can also be used with ')' )

COOL BITS
ctrl + a - hops to nearest number and increments it

WINDOW MANIPULATION BINDINGS
ctrl + w + o - close all window buffers except for the one selected
ctrl + w + v - open up a vertical split window
ctrl + w + s - open up a horizontal split window
ctrl + w + r - rotate windows


/ simple search command
: enter COMMAND mode

INTERESTING CHAINS
:1,40d - Delete line 1 to 40 included
:2,$d - Delete every line from the second one to the end of the file
:.,$d - Delete every line from the current line to the end of the file
:%d - delete every line

FROM NORMAL MODE, ENTERING OTHER MODES
i - enter INSERT mode at the current cursor position
a - enter INSERT mode at the following cursor position (appending)
shift + i - enter INSERT mode at the beginning of the line
shift + a - enter INSERT mode at the end of the line
v - enter VISUAL mode
shift + v enter VISUAL mode and select the current line
shift + r enter REPLACE mode (think of this as INSERT in windows/mac, simply replaces all text beneath cursor while in this mode)
ctrl + v - enter VISUAL BLOCK MODE
shift + v - enteri VISUAL LINE MODE

NO MATTER WHAT MODE YOU'RE IN, you can always:
<ESC> to return to NORMAL MODE
ctrl + { to return to NORMAL MODE

COMMAND MODE
:w - writes (my nneovim setup as autosave, but it's still a good feature to have)
:q - quits neovim (first neovim command to learn)
:wa - writes all files
:wqa - writes all files and quits
:e ./name_of_file_to_open - not as good as fzf, but is a decent native file finder in nvim

INSERT MODE
tab - configured for four spaces in my case

VISUAL MODE

h,j,k,l,g,shift+g,0,$ all apply, it simply highlights them
and you can use standard and custom commands here that would normally apply in NORMAL mode


VISUAL LINE MODE
y - yank the line (more useful than yy, will past without having to create a new line)

--Custom Keybindings

NORMAL MODE

nf Simply typing this in NORMAL MODE will invoke Neoformat, simply hit enter afterwards

CTRL + p or fzf Simply typing this in NORMAL MODE will invoke FuzzyFileFinder, simply hit enter afterwards

rg Simply typing this in NORMAL MODE will invoke RipGrep, simply hit enter afterwards

cmp To toggle code snippets

CTRL + V ENTERS VISUAL BLOCK MODE
I only really use this for muliple commenting out of lines
(ctrl + v + j or k and then ctrl+c to comment out code)

SHIFT + p Automatically Updates new Packages with :PackerSync

CTRL + x removes highlighting from previous search results

CTRL + c Comment out line (use in conjunction with CTRL + V for multiple lines)

CTRL + j/k Enter Multi-Cursor (red cursor is NORMAL MODE< yellow cursor is INSERT MODE) (hit <ESC> to return to NORMAL MODE - might require hitting <ESC> multiple times)

SHIFT + m Open up Markdown Preview for .md files (mainly used for README.md)

CTRL + p Open fuzzy file finder like search application

CTRL + o Return from gf (navigate to file)

:Neoformat Formats most code options (don't use with .c or .cpp files as there is another application i use for that)

cp alias for using ClangFormat C/C++ Formatter

CTRL + b : Open Nneovim Tree
in Neovim Tree there are specific keybindings (most standard neovim keybindings work here as well):
a - creates new file (keep adding slashes to create directories or don't for regular files)
d - deletes file (hit y when prompted)
r - renames file (enter new name and hit enter)

/ search for a word in whichever document you have Open

CTRL + v open file in Nneovim Tree in new vertical workspace
(if more than 2 are open, Nneovim will ask which one you wish to open it next to, A or B or C etc)

CTRL + h Navigate to one vertical window to the left
CTRL + l Navigate to one vertical window to the right

CTRL + e to adjust window width (h and l will adjust width, just hit enter afterwards to adjust, opening and closing nneovim tree readjusts back to defaults)

t open new tab

SHIFT + k goes to next tab

SHIFT + j goes to previous tab

SHIFT + S Aliased to global search and replace
SHIFT + Y Aliased to inline search and replace

F11 Toggle Spellchecker

Custom shortcut: nv (opens up new vertical pane)

-- INSERT MODE
# deprecated when OKLB acquired...
ii - equivaent to <ESC> key (return to normal mode from insert mode)

-- ESPANSO BASED commands
NOTE: Espanso can be used in conjunction for some powerful aliases in neovim (as well as other applications)
FURTHER NOTATION: Please note that espanso is capabale of a lot more than is featured here and I highly recommend coming up with further expamples as it has the potential to greatly increase workflow speed
SEE: https://espanso.org/

Here are just some of my favorite expanded texts
In NeoVim's INSERT MODE, simply type

:command-prepended-by-colon - expands to this
