This is a cheat sheet for how to perform various actions to ZSH, which can be tricky to find on the web as the syntax is not intuitive and it is generally not very well-documented.
| Description | Syntax |
|---|---|
| Get the length of a string | ${#VARNAME} |
| Get a single character | ${VARNAME[index]} |
| " documentation and source are credited to https://github.com/mgarort | |
| " Make vim-sneak mappings more consistent in visual mode by making s go to next match and S | |
| " go to previous match, while keeping vim-surround functionality through z | |
| " (mnemonics: vim-zurround) Explained in this GitHub issue: | |
| " https://github.com/justinmk/vim-sneak/issues/268 | |
| " | |
| " So now the behaviour is: | |
| " - Normal: s and S to move with sneak | |
| " - Visual: s and S to move with sneak, z to surround (zurround) |
