As far as I can see, there is no hotkey for cyclying between SELECTED units of the same kind.
Let’s say I select all my barracks and I’d like to go individually through all of them. Well, there is a specific key for each building type (i.e the barracks key, the markets key, etc. … but there is not a generic hotkey for cycling through SELECTED units (regardless of the type).
Imho, this is a pretty basic feature. Am I wrong?
