A bit of info I can't find anywhere:
Is it possible to choose a key combination to launch the Start11 start menu?
I am thinking of CTRL Win or Alt Win.
Or could this be added in an update?
In the Start11 Configuration Control settings you can set the left Windows key to open the Start11 menu, and if you have a right Windows key on your keyboard you can set it to open the Windows Start Menu. If you don't have a right Windows key, you could remap another key to the right Windows key. For example, remap the right Alt key to the right Windows key.
You can also set clicking the Start button to open the Start11 Menu and Ctrl+click the Start button to open the Windows Start Menu.
NOTE: You can use Microsoft PowerToys' Keyboard Manager module to remap the keys.
