Each track in LEGION Simulator Timeline has these three icons:

• Click to enable or disable the track. When the track is enabled, the green tick shows, when disabled the tick is crossed out.
• Click to lock or unlock the track. When a track is locked, you cannot make any changes to it.
• Click and select a colour from the pop-up palette for events on the track.

Status icons

Just to the right of the Track names, there is space for one of three icons which indicate its status:

• Ok to play back.
• Warning issued which may need attention, but will play back.
• Error detected, will not play back until remedied.
