Sometimes, while using keys to navigate between rems etc., the right-click menu of references is triggered (for example, when going up a few rems using the ↑ key to a rem that is only a reference, e.g. the Aliases reference). As of now, there is no way to exit this besides clicking somewhere else with the mouse.
It would be much more convenient to be able to exit this menu using the Esc key (same as for exiting the / menu).
