Advanced VIM commands

This only covers the commands which I deem “advanced” i.e. I shouldn’t forget but I usually do

• ctrl-o(Insert mode): enter command mode but go right back to insert mode upon finish
• gJ: join lines without adding space in-between
• gu or gU + action: change to lower/upper case
• :bd – only close current file, not the whole vi window
• macro: record with qw  do something q; and call it with @w (w can be any register name)
• a/i/t (all/inside/till) operation. e.g. ‘ci”‘ change everything inside double quotes (exclusive)
• :e reload changes from disk
• Ctrl-G : show file info

• :r !cmd

  filename : run a command or from a file, read output into vi

• m and ‘ : set and got to bookmark
• ‘0 : go to last place when vi exited

• z+{.

  -

  Enter}: make current line at the screen Top/Bottom/Centre

• :set list/nolist: show line feed
• :tabn,:tabp,:tabe {filename} : Use tab for multiple files
