" Learning
" basic toolbelt: r,ysp,hjkl,xd,uC-R,v,:eE,iIaAoO,bBwWeE

" 'fx','Fx','tX','TX' find and 'till motions
" 'c' for replacing
" 'A' for appending at the end of line
" 'I' for inserting at the beginning of the file
" '.' repeats last command
" '#gg' go to line #
" 'G' to go to last line
" 'gv' to reselect last block
" 'ctrl-o' and 'ctrl-i' to go back and forth between cursor positions
" 'ctrl-o' in insert mode allows a normal mode command

" 'ctrl-r ctrl-w' in command mode pastes the current word in the command line

" '%' for searching matching parentheses/braces/brackets
" '/' and '?' for searching patterns
"   - 'n/N' to move between apparitions
"   - 'gn' if an operator is pending, operates ONLY on the match
"     (without it visually selects the next match, but I don't care)
"  Replacement Options
"   1. ':.,$s/foo/bar/gc'
"   2. '*' then 'cgn' then 'bar<ESC>' then '.' ...
"   3. '*' then 'cw' then 'bar<ESC>' then 'n' then '.' ...
" '*' and '#' for searching words
" 'g*' and 'g#' for matching words

" ':s' search and replace
"  - 'g' flag allows multiple replaces in a single line
"  - 'c' flag asks for confirmation
"  - ranges: '%' all file, '.,$' from current line until the eof

" tip: an empty string will repeat a search pattern (?)
" tip: command + search pattern
" tip: command + count + motion

" Maps
" Commands are mapped, not keystrokes! It's misleading because that's what it looks
" like sometimes. For example, given the map 'h' -> 'y', pressing 'h' inmediatly sends
" an 'y', but this behaviour changes if there're other commands with the command
" mapped as a prefix. If the map were backwards, 'y' -> 'h', pressing 'y' gives you
" a window were an 'y' is on hold, and only after a while it registers as an 'h'
" Also, 'non-recursive' means that the definition is non-recursive, not something else
