I didn’t know how many times I miss click the ALT key before switching to ST4, but apparently now on Ubuntu 18.04 with Gnome when I click on the ALT button the menu bar is shown with the first entry selected, the File, but then the entire Gnome session is locked until I click ESC to hide the menu bar in Sublime. I can’t even navigate away using Alt+Tab, nor the super key, nothing.
Is there a way to disable this, I can’t find the key bindings for it.
EDIT: this happens only when the main menu was hidden - Ctrl+Shift+P - View: Toggle Menu. When menu is hidden in ST4, clicking Alt shows the menu and locks the keyboard for anything outside that menu, in ST3 clicking Alt doesn’t do anything, which is the behavior that I want.
EDIT2: that was easy
{ "keys": ["alt"], "command": "" },
or even having
{ "keys": ["alt"], "command": "toggle_menu" },
helps, because it simply shown the menu, without selecting the File item and therefore locking everything else
