Other "z" commands (these are the ones I always get mixed up):
:setlocal spell spelllang=en_us - turn on spell check
z= - bring up list of suggestions
zg - add word to dict
zug - undo add to word
zw - mark as wrong
zuw - undo wrong
:help fold
zf<motion> - create fold (common motions '%', 'a{', 'a(' )
zo - open fold
zA - open folds recursively
zc - close fold
zd - forget fold
zj - move to next fold
zk - move to prev fold (up)
zg g = Good word, add to personal dict
zug Undo Good word.
zw obviously, Wrong word.
...
zo Open
zA open All
zc Close
zj uses the same movement as the j key
zk ditto
Once you have the mnemonics sorted, sometimes you find you can remember the others because they are the ones "left out" of those with mnemonics, like zd doesn't have a mnemonic, so the command left over is "forget fold", so zd is that one. After a while, muscle memory takes over.
Yeah, I like the fold commands, which I barley discovered a few weeks ago. I typically do "set foldmethod=indent" then pres "zr" multiple times until I'm at the fold level I want. Then I can just do "zo" on the parts of code I'm interested in.
