Select a fleet/planet, science ship/colony ship/etc, and press Ctrl+(any number). Now, those units are bound to that number and you can press that number to instantly target (double press to jump to) that unit. You can group multiple fleets, science and constructions ships, really anything you can micromanage.

You can Setup to 10 groups. (For 10th group, use number 0). They change often, but can save UI navigation time.

To unassign select the fleet, ship, colony, or planet etc and press Ctrl + number you want to unassign.


If you have a science ship set as a control group, you can use the hotkey to select the science ship even when it's "MIA" from Experimental Subspace Navigation or combat, allowing you to easily reassign scientists mid-flight
