Selection Rank
Selection rank is what decides which units will be selected when doing a box drag over multiple unit types such as fighters, builders, buildings. There are 4 selection ranks 0,1,2,3. 0 is for buildings 3 is for fighting units. When doing a box drag over units with different selection ranks, only the units with the highest rank will be selected. You can see a units selection rank as a large grey number on the side of the command menu, generally fighters are 3, builders are 2, buildings are 1. You can change a units default selection rank in the in game settings, for example commander set to 2 will avoid accidentaly cancel building queues or killing your com.
You can bypass selection rank this by holding shift while dragging, you will select all units/buildings in the box.

Autogroups
Ever wished to have all fighters in group 7, all gunships in group 8, all raiders in 4 etc? Autogroup achieves just that.. Auto grouping is feature of ZK (widget) Alt+number - makes permanent "auto group" out of currently selected unit types New units then join that group when they first become idle. Alt+~ - removes currently selected unit types from the autogrouping. Ctrl+~ - selects ONE unit out of currently selected units (closest to your mouse cursor) and removes it from any groups (not removing type from auto group, just current unit from group). Autogroup settings can be modified from the in-game menu: Menu -> Settings -> Interface -> Control Groups Example use: Select a Glaive and a Warrior and press _alt+1_. From then on, new Glaives and Warriors will join group 1 when they first become idle (after reaching factory waypoint). You can press 1 to select them. If you then want to add Zeuses to autogroup 1, select one and press alt+1. If you then want to remove Glaives from autogroup 1, select one and press alt+~.
