Use sequence In and Out to set Marker In and Duration

Creating range-based markers is overly complicated. Why not have an option to create markers from In/Out points. As it is now, to do this, one has to set the in and out point to calculate the duration, then copy the duration, then go back to the in point, add a marker, then edit the marker and paste the duration. This new command could be available in the keyboard shortcuts so that the user can define their own command, much like set marker colors.
