Just to check, is this assumption based on Shell bindings, or Vim bindings?

I've always used Ctrl-w to delete the previous word in vim, and that binding works fine in any of the menus. Similarly, Ctrl-u works to delete the entire line.

That said, I do remember someone else raised this issue, so perhaps its worth adding an option for it, or making sure rebinding it is easy.

This assumption is more based on OS bindings I think. Since the input bar pops out with its own UI, it felt disconnected from the editor/vi and it was my natural instinct to use hotkeys that work across my os (OSX).

[Speculative]

I was curious about this a little while ago and found where input key events are processed.

AFAICT this wraps a regular HTML text input element. The reason ctrl+ platform-specific bindings aren't working (which should come for free with Electron) is this switch/case defaults to swallowing keybinds that it doesn't recognize. I wasn't sure if this was a bug or a feature (I personally would like to Ctrl+A to select all, which is a habit that carries over from the way I interact with text inputs in the rest of Windows).

Regardless, it seems like a pretty case-by-case kind of basis. We can patch in these keybindings if we want to?
