Since I am using Ubuntu 18.04 and later the alt key to toggle the menu does no longer work. I think this is already integrated in sublime core and does not need a keybinding.
When I try to do that it gives me this error in the console:
Unable to parse binding {command: toggle_menu, keys: [alt]}
for the binding:
{ "keys": ["alt"], "command": "toggle_menu" },
instead, the following work:
{ "keys": ["alt+1"], "command": "toggle_menu" },
To confirm ALT does not toggle the menu I deleted .config/sublime-text-3
Does SublimeText have a build in key binding (Alt) for toggle_menu?
I think there is some problem with Sublime and Ubuntu Gnome Desktop Environment.
Edit:
I confirmed Alt works to toggle menu on Windows 10. On Linux, hide menu does not make a difference.
