Go to Marker Number 6    𝍖6

Move the playhead (and display) to marker number 6. These commands are assigned to the extended keyboard numeric keypad.

I would interested in trying something like “Go to marker by name” where you can search by title. The “Go to marker n” where you type in a number costs an extra couple of key presses, but would free up a numeric keypad.

In a significantly long or complicated project keeping the Marker List window open would seem to be a better approach.
