[Feature] Add hotkey to focus on input text

[nikitavoloboev]

Feature description

This input box. It's often not in focus and only way to bring to focus is to manually hover over input or press tab many times. I'd love if ideally it's either always in focus or have a hotkey to move focus to it quickly.

You could add a hotkey that triggers the focus, similar to code here: #550

And here's another one showing how to add custom hotkeys: #109 (comment) (you'd want it to trigger focus on the text input box, not click the new chat button).
