The focus style for the Keyboard Shortcuts on/off toggle switch is difficult to see in the high contrast theme and does not match the toggle switches of the Sound Options dialog

[sbates-idrc]

Focus applies a black border around the toggle switch, when its outer colour is black.

Additionally, the toggle switches on the dialogs are styled differently from the pen up/down and add node expand/collapse toggles on the main UI. Review those designs also.
