It would be great if we could also display chords in the mapper tool, similarly to VSCode.

I dug into this a bit and it's more complicated than I expected. If you just have a timer and track keydown events, you get chords likeMeta Meta+b because the keydown forMeta is different from the keydown forb. It looks like this is solved in the main code with the 'radix trie' logic, but this seems pretty closely tied to the hotkeys that are configured on the element, and we can't configureall possible hotkeys onto the mapper tool.
