Add keyboard shortcut to Remove marker at playhead in Timeline Panel

I want a shortcut I can use in the Timeline panel to remove whatever marker the playhead is on, whether the marker is on a clip or on the sequence. 

I know I can edit a marker (either with the Edit Marker shortcut or just by pressing the default M on a marker) and then press Delete, but that's a 2- or 3-step process. I know I can remove a selected marker, but it seems that's only when I'm in the Markers Panel. There's a shortcut for removing all markers, but not a single one at the playhead. 

Thank you for your consideration.
