Feature Request: global hotkey to re-run last command

Description of the new feature/enhancement

I would really like to see the ability to bind a global hotkey to repeat the last command in the visible terminal. In essence all it does is: up arrow and enter on the terminal that is visible. Should work even when terminal has no focus since I'm pressing this global hotkey when I'm not in the terminal.

Global hotkeys should be bindable to any key, including special keys such as Scroll Lock, Pause/Break and the Context Menu (the button next to the right CTRL).

iTerm2 has this functionality and no other terminal emulator I've tried has this, on Linux or Windows. I'm sure this is achievable with AutoHotkey but I'd prefer native functionality.

Use case for me:
When testing or running experimental scripts, it is common to rerun your script every time you make a change. It is very productive for me if I don't need to take my hands off the keyboard for this. Personally I would bind this functionality to the "context menu" key (between CTRL and Windows), since I never use that button anyway.

The issue names no files, tests, or entry points. Begin by locating the terminal's command-history handling and global key-binding or input registration paths, then verify that a configurable unfocused hotkey repeats the last command in the visible terminal, including the requested special keys.
