HotKey use

The Hotkey of WordPress, I think, works with Alt + Shift + Key. Press Alt + Shift + Letter to make these commands. On my tests, currently, works this only on the visual editor, not on the text mode. But I use this not realy, I have only use the functions of the WordPress Core to provide this function, see here for the access key – https://codex.www.ads-software.com/Quicktags_API#Parameters
