Qia.KeyboardShortcutHelper: Use Case 01: I want to use shortcuts such as "Space", "Ctrl+Backspace", "Ctrl+Z", "Shift+3", "Alt+F1" and "Ctrl+Alt+Q" for my actions without bothering to know the details of keydown, keyup and other events.

Hints

Press any shortcut in [ "Space", "Ctrl+Backspace", "Ctrl+Z", "Shift+3", "Alt+F1", "Ctrl+Alt+Q" ] to check reaction results.
