These are the vim folding commands that “fold” certain lines in the file in order to help you focus at certain part of it:
zf#j creates a fold from the cursor down # lines.
zf/string creates a fold from the cursor to string .
zj moves the cursor to the next fold.
zk moves the cursor to the previous fold.
zo opens a fold at the cursor.
zO opens all folds at the cursor.
zm increases the foldlevel by one.
zM closes all open folds.
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.
[z move to start of open fold.
]z move to end of open fold.
Ex like range commands also work: e.g, “
:10,20 fold” will fold lines 10 through 20.
You may use the following in your
~/.vimrc file to automatically fold lines when you indent them (for example in a program file):
