Search only in selection

• Select where you have to find something.
• <ESC>
• Prepend \%V to the search:
  • /\%Vpattern

Search for a pattern then from there for another pattern

/string1/;/string2

Repeat last ex-command

The last executed ex-command is stored in : register, thus you can execute it through the @: then @@.

Scroll windows synchronously

:windo set scrollbind

Switch vertical split to horizontal split and vice-versa

• Switch to vertical: ctrl+w + H
• Switch to horizontal: ctrl+w + K

Check for some already associated map

:verbose map [keymap]
