This is related to several other Key Command Requests. Most directly: Select Project Window.
When one is using the Notepad, it necessarily has to hijack lots of keystrokes in order to be able to type. So most Key Commands don’t work.
Unfortunately, there doesn’t seem to be a key command that lets one switch focus BETWEEN Notepad and Project or MixConsole. IOW: you -always- have to use the mouse to swap focus off the Notepad. That’s BAD.
There needs to be a key command in Notepad that says ‘Pay attention to Key Commands now’. Perhaps tapping Alt would do this.
Eg… when you tapped Alt, you could then hit F10 (what I use to go to MixConsole1) or Ctrl-W (what I use to go to Project).
