[Feature Request] ESC to close dialogs and panes

In many KDE apps, e.g. Konsole, hitting ESC is used to quickly close an opened dialog w/o mouse interaction. It'd be convenient to have this in Kalendar in order to close for example dialogs such "Edit Event" etc.

Also if ESC closed the "Event view pane" on the right side, it would make this action much quicker (for me).
