Support for key handlers during "choose"

[dkpalmer]

Is your feature request related to a problem? Please describe.
"choose" TUI doesn't enable number/letter shortcut selection

Describe the solution you'd like
I'd like to prefix "choose" list entries with a number, and support selecting an option with one of those numbers in addition to "Return" on selection.

Describe alternatives you've considered
"filter": Unfortunately, UI is not ideal in this use case.
