Move end marker to playhead

Recommendations on a lua script starting point to move the end marker to the playhead with just a key combo?

I often record a bunch of demo ideas in a row, and just append on the end. At some point, the end marker stops jumping to the end of my latest recording. Yes, I can right-click on the end marker and select “move marker to playhead”, but I’d like to keep my hands on the keyboard. Thanks!
