Relative Position ⌃⇧R – Logic Pro keyboard command of the day

  Relative Position  ⌃⇧R

Show the MIDI event positions in a region as if the events occurred with the beginning of the region at the start. This can be very useful when working with region that may repeat at different points in a project. Handy. If Relative Position is set then Show Event Position and Length as Time will cause the position to start at 00:00:00.
