Key Command or other way to resize event with timestretch?

I have some long wave files with some percussion recordings and I need to resize some of them so that the transients perfectly line up in the middle of the events. I want to zoom in close to the middle of the event and while zoomed in… resize with timestretching applied.

Obviously when zoomed in, I can’t use my mouse to drag the event end position since it is off of the screen. Is there anyway to do this with a key command or menu choice?
