Add support for global hotkeys

[khanxmetu]

Problem Hotkeys do not trigger when the focused element is an input or textfield.

Suggestion Add opt in support for global hotkeys that fire even when focus is inside some input form/textarea. There are cases where certain shortcuts (e.g Ctrl+S to click save button, Ctrl+K to click a command palette) should work everywhere including when the user is typing in some textarea.

The feature is similar to Mousetrap’s Global Bind.

Possible Implementation

Introduce a data-hotkey-global attribute:

<button data-hotkey="Ctrl+s" data-hotkey-global>Save</button>
