Slip Event.. but via nudge?

In Preferences > Tool Modifiers > Select Tool there is a modifier for Slip Event which is pretty handy… but it seems like Slip appears nowhere else in the interface, that it’s only an interactive drag operation. Ideally I’d like to be able to use it with Nudge, so I can slip an event by frames or whatever timebase I’m in. Is there a similar function called something else that I’m just missing?

I know I can nudge and then trim left/trim right to put the event back into place, but it’s a bunch of steps to do something so simple. And using the Slip Event modifier doesn’t snap to the grid either which would have been a good enough crutch.
