There are many other Ctrl+"key" shortcuts for quick access to important menu entries. These shortcuts are shown if you open any menu and therefore are not mentioned here.

It's also possible to use the keyboard to control the menu (e.g. Alt > F > O to open a file). Use the underlined character after pressing Alt in order to call the menu action.

Important note for Mac users: Every instance of the "Ctrl" button should be replaced by the "Command" button
