TIWCGJQLayoutPanelOptions.CustomHotkeyModifier Property
Custom hotkeys must be pressed in combination with either the CTRL or SHIFT key - or both together. Use this option to choose which modifier-key(s) to use with the customHotKey. If this option is missing or invalid, "CTRL+SHIFT" is assumed. NOTE: The ALT key cannot be used because it is not detected by some browsers.
