Starcraft – Select all probes at main

starcraft-2

Looking at replays, keeping the player camera mode, I see some players select all probes they have at their main while having their view elsewhere.

How can this be done?

Thanks

The only possibility in my mind is command groups. At a previous time, he selected a batch of probes, held Shift or Ctrl and pressed a number, 1 - 0 (number row only, not keypad). When looking elsewhere, all you have to do is press the assigned number in order to recall that selection.

Holding shift+# adds the currently selected units to the selected command group. Holding ctrl+# creates the currently selected units in the selected command group.

shift = additive
ctrl = replace
