Finally, click one last time to go to the sixth option:
This is a new display that shows each unit’s Time Stamp. You can imagine how useful this will be for combat planning. (Every unit is at zero in this display since no units have moved yet. As units move, the values increase until, when all movement allowance has been expended, the value will be 10. (Timestamp is the combat round that the unit is on). Note that it takes quite a number of clicks to go from the first option to the timestamp. However, right-clicking the button cycles in reverse. So a right-click can take you from the first option directly to the sixth one.
