Feature request: Pressing 2+ modifier keys to release the mouse, instead of Escape

[bradtchapman]

The 'Escape' key is used a lot in Windows to trigger the "Cancel" button or to close menus. Since Windows 95 has mapped this button for itself, it's not possible to use Escape within the Electron Windows 95. Furthermore, attempts to use combo keys with escape result in that key being stuck down inside Windows 95 until the user manually presses and releases it.

It would be great if this Electron app used a key combination with multiple modifier keys to release the mouse. For instance, in Parallels and VMWare, you can press Cmd-Opt to release the mouse. On a Windows and Linux host system, you could use Ctrl+Alt instead.
