Problem Statement

When I’m using voice in Claude Code, I have to press and hold the spacebar to activate it. It’s quite difficult to keep holding the spacebar while speaking. When I hold it down, it keeps triggering a couple of spaces continuously. I’d like to change it to a different shortcut if possible.

Proposed Solution

Able to change to some other key.
