I'd love to give this a try over the weekend if I could get some high level direction on how to achieve this (or a similar commit)

Doing some research into this, tell me where I'm wrong:

• Vim delegates to Editor or other crates for functionality
• Editor has popups here
• Popups render a "div" by delegating to gpui here

The main issue is that this div does not have any interactivity to the same level of a editor itself or at least an "editor-lite". Ideally there'd be an editor command like "FocusPopover" that would move the cursor into the popover and subsequent q to move to the previous focus (I think that's how it works).

So I think it'd have to be:

• Implement interactivity in popovers first (As of now you can't highlight text even with a mouse)
  • This one is probably the trickiest and where I'm struggling with where to start as the popover looks to be a readonly static render of data queried from the LSP, not like a "editor lite"
• Implement a "FocusPopover" command or maybe "TogglePopoverFocus"?
• Implement a Vim binding that would call this command

@NukaCody youre exactly right. I know @mikayla-maki had some ideas for making text in gpui selectable, but I don’t think that’s happened yet.

probably the easiest path forward would be an action to either copy the text in the popup, or open it in a new buffer/split.
