keycodes: https://gist.github.com/awidegreen/3854277

let's talk about modes! 
there are 3 modes. 
"n" (or normal) mode
"i" (or insert) mode
"v" (or visual) mode


keyboard shortcuts that i use a lot:

down - j
down 5 lines - 5j
delete line - dd
delete 20 lines - 20dd
delete to end of file - dgg

yy - yank and paste
:reg (registers)

/ (search)
? (reverse search)
:line_number

[{ & }] (code block jumping!)

running commands `!`

pattern match & replace

[I (show all uses of this word)
* (jump between current word)

split screen, and navigating between them 
tmux & ^Z

buffers! (opening multiple files)

writing a custom key binding:

try this 
:%!python -m json.tool

shorten this to a command

:command JsonFmtAll %!python3 -m json.tool

(run :JsonFmtAll) . this is a lot to type. let's make a shortcut for it

:nnoremap & :JsonFmtAll<CR>

that's great. but what if my file looks like this:

{ "json":"this is", "some" :"json" }

Not Json.

here's another command

:command -range JsonFmt <line1>,<line2>!python3 -m json.tool

great. now we want to remap a key, but only when in visual mode

:vnoremap & :JsonFmt<CR>


here's what i put in my .vimrc file

" Fast JSON formatting
command JsonFmtAll %!python3 -m json.tool
command -range JsonFmt <line1>,<line2>!python3 -m json.tool
nnoremap & :JsonFmtAll<CR>
vnoremap & :JsonFmt<CR>
