Short Key
The properties applied to Button and ToolbarButton allow you to set keyboard shortcuts.

In the browser, keys like F1, F3, F5, F6, F7, F12, Tab, number pad keys: /, +, -, and Backspace cannot be used as a Short Key. Single keys like F2, F4, F8, F9, etc., can be used. For other keys, you can use a combination of keys such as Ctrl, Shift, Alt, or Windows key with another key as a compound key method.
Example: Ctrl + a, Ctrl + Shift + 1 etc.
