vim tips and tricks

help

The most import thing to learn about in vim is...

:help

and

:help command

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).
