Currently users must click the check mark on a Marker Track to make it active. I rely heavily on key commands & macros to speed my workflow (+ full custom Lemur templates), and I was not able to find a place to map a command for this.

Or at least a better way than the current. I keep my tracks at 1 row height. It’s not possible to move the “Activate” button in Track controls settings so it’s always on the second row. There’s nothing in the inspector to activate the selected marker so I have to change the height of the marker track just to activate it.
