There is no keyboard shortcut for going full screen as far as I could see.
Also, this trick doesn't work either: http://osxdaily.com/2011/08/10/full-screen-keyboard-shortcut-mac-os-x/
I assume this is related to the fact that at reboot, the app doesn't restore in full screen like it was before rebooting.
👍 This is something I'd really like too! Even the menu item, which would allow that trick, would be great!
Yes, please add a menu item & keyboard shortcut for full screen.
