[FEATURE] Escape button should not be doing 3 different actions

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

Right now, when I'm pressing the escape button multiple times in order to clear the text or to switch into rewind mode, it also stops all the subagents. Sometimes I need to just rewind, but it clears the text. Sometimes I need to clear the text, but it stops all subagents, etc.
This is because it's doing three different actions simultaneously.

Proposed Solution

There should be three different key bindings for these 3 actions.
