The zsh docs are good for the zsh specific expansions, but more man page than cheatsheet, though they do have an intro doc on it that's more cheatsheet like but less complete.
Also strips the path and you have to know the extension name(s). For my examples, "cut" would be appropriate. But those substitutions tend to work in anything POSIX, not just bash/zsh.
Do you know of a cheatsheet that describes what all the percentage sign means and other things you can do with parameter expansions?
