The magical shortcut all begin with z. Type :hep fold to learn more about them.
These are the most common shortcuts in my personal order of preference.
- zo opens a fold at the cursor.
- zc closes a fold at the cursor.
- zM closes all open folds.
- zO opens all folds at the cursor.
- [z move to start of open fold.
- ]z move to end of open fold.
- zj moves the cursor to the next fold.
- zk moves the cursor to the previous fold.
- zf#j creates a fold from the cursor down # lines.
- zf/string creates a fold from the cursor to string .
- zm increases the foldlevel by one.
- zr decreases the foldlevel by one.
- zR decreases the foldlevel to zero -- all folds will be open.
- zd deletes the fold at the cursor.
- zE deletes all folds.
