Control Group + Tab Control? Possible? If yes, how?

[JPM]

Ok, so I've been watching some YouTubers play Forts, and Frazzz in particular got me to finally buy the game myself, and now have 42 hours of play time under my belt. I've gotten pretty good at it now (despite the s---ty ping here in Asia, not a lot of players from where I am T_T ), but there was one thing I couldn't do that I only saw done by MasterofRoflness, a YouTuber.

After he groups the mortars together in one control group and aim & fire them together at the area he wanted, he would use the control group again, but this time he is able to fire them one by one with just the control group he selected and without the other weapons firing, like how it does with the Tab control to cycle through all weapons. How do you do that? Or am I just stupid and mistook what he did?

P.S. - Please be gentle if I was wrong and was just being stupid :P

If you right click in the aiming arc of a group, it will fire the units one at a time with each right click.

Wow, so it does exist. Thanks a lot!
Also, can I report what I think is a bug in the Campaign mode? Whenever I zoom out the screen just suddenly shakes up and down a lot, making it look like pixelated and impossible to aim weapons. The only way to stop this is if I zoom in, then zoom out again so I can properly aim. This never happens when I play Skirmish or Multiplayer. If it's not a bug and is just caused by how low my laptop's specs are and you guys cannot help, then it's alright, I've finished the campaign anyway on Hard, 3 Stars all. I just thought you guys would still need to know this. Again, thanks for replying.

That screen shake issue is a bug. Can you tell me which map that was occurring on?

So sorry I am replying only now. Steam only notified me of your reply just this day (07/20/2017 from where I am). I forgot which missions had this "screen shake" as you call it, because I already finished the campaign, and university caught up to me and got me really busy, so I rarely played. So I tried randomly revisiting some of the missions from all 3 factions today, and in every mission I replayed I didn't encounter this screen shake issue anymore. I remember Forts having some updates days later since encountering those screen shakes, so maybe in one of those updates the screen shake issue got fixed? I'll try playing the whole campaign again when I have the time (probably on Saturday, 07/22/2017) so I can double check the whole campaign if it's fine now. Again, so sorry I only replied now.
