vim tips and tricks
help
The most import thing to learn about in vim is...
:help
and
:help command
- TAB - cycles through possible command completions
- CTRL-d - lists possible command completions
For example, try
:help tags (then CTRL-d and TAB)
Do help i_ CTRL-d for insert commands, v_ for visual, etc.
Also, when in the help pages, CTRL-] jumps to subjects between |bars| and CTRL-T jumps back (and, of course, :q to quit).
