These are notes I’m taking as I play vim golf; this is meant to be useful to me, maybe not you

• Record a macro:  q<letter> <do stuff> q
• playback that macro @<letter>
• :set number (show lines numbers)
• :g/<searchString>/norm <vimcommands>  (search for searchstring and run vim commands)
• :g/<searchString>/<ex command>  (d delete) (multiple ex commands sep by | )
• <ctrl-r> = <MATH EXPRESION> (while in insert mode does math and prints answer)
• <ctrl-r> % (insert the file name)
• <ctrl-r> = “\escapecode \x73\x75\x70\x65″  (will un-escape the escape codes)
• * (jump to the next occurrence of the word you are currently on top of)
• %s//<replace>  (replace your last search with <replace>)
• *%s//<replace>  (replace all occurrences of what is under your cursor with <replace>)
• Replace all tabs with 2 spaces : :set et ts=2<CR>:ret<CR>
• ctrl-v : visual “block”  select a box (not entire lines)
• f <char>  : jump to next <char>
• v (enter visual mode) <select>  then :s/search/replace  (replace in visual selection)
