DevTools has keyboard shortcuts -- you can view a help screen by
pressing the '?' button. However, they only work when the DevTools
window has focus. For your issue, please consider using 'Event
Listener Breakpoints' on the right of the 'Scripts' panel.
Perhaps there is (or can be) a binding, but just to note: you can use
the Event Listener Breakpoints to break on 'click' only.
