[Feature request] add a way to open the three-lines menu with the keyboard

[bzzrak]

There is no way to open the 3-lines menu with the keyboard. I propose that it is added. Pressing the Alt key alone to open it would probably be best and in line with the classic notepad.

Agreed, I will do it.

@JasonStein Can I take a shot at this? And could I also take a shot at adding the ability to change the default keyboard shortcuts in settings?
