zsh: Autocomplete ambigously only on second tab press

Question

Currently, when I hit TAB, and there's more than one option to autocomplete, zsh will show all of them. If I hit TAB a second time, it will pick the first.

I'd like to change this to:

1. First TAB: Do nothing if there are more than one option
2. Second TAB: Show the list
3. Third TAB: pick the first

Is that possible?

(Why? When I hit tab, it's usually because I think what I typed was unambiguous. If it's not, I want to stop for a second and look back before getting the list.)

In addition, how do I turn on menu-based completion (where I can choose the choices from a menu)?

Answer 1

in ~/.zshrc

unsetopt BASH_AUTO_LIST

With BASH_AUTO_LIST set, the list only appears the second time you hit tab on an ambiguous completion.

Take a look at Ambiguous completions section for more options
