Is there a way to update a Binding description?

[leemthai]

Hey Guys,

I would like to make some of my bindings context-sensitive e.g. say "Turn Feature On" (if off) or "Turn Feature Off", that kind of thing.

It seems like there is no mechanism to update bindings once created?:
"Textual doesn't support modifying the bindings at runtime, but you can accomplish this with dynamic actions which offers greater flexibility."

If that is correct, is there any other to accomplish my goal of context-sensitive key binding descriptions?

Cheers!

It's right in the quote: dynamic actions. https://textual.textualize.io/guide/actions/#dynamic-actions

Define two actions, one for on and one for off, and implement a check_action to define the logic regarding which is displayed.

I'm not getting any dimming at all for disabled keys, whether in my own app or in the sample app code from here:
https://textual.textualize.io/guide/actions/#__tabbed_4_3
actions07.py

I'm running Textual 2.1.2

Your terminal has a bug regarding applying dim to RGB colors. The latest version of Textual as a workaround.
