//=== CONFIGURATION BEGIN
//`key` is the key name. If it's a letter, it must be in uppercase.
//`mods` is a zero or up to 3 modifier key characters (in any order): `A`=Alt, `C`=Control, `S`=Shift. Character case is ignored.
// e.g. "" (no modifier key), "s" (Shift), "Cs" (Control+Shift), "aSc" (Control+Shift+Alt).
//`name` is the hotkey description which will be added onto YouTube's Hotkey List Popup (accessible via `?` or `SHIFT+/` key).
//`func` is the JavaScript function to execute with the activated hotkey object as the first argument.
