Nice puzzle... i don't get the clue for debrief? CTRL+O is open, so GOO?
For 3D, Lingo came first: "While Lingo may seem like it's a rip-off of Wordle, it's actually the other way around. Lingo was first broadcast in 1987, and is only now being rebooted"
*control post, control freak, go commando.... ok i get it now (i don't own a mac so had to google it)... i just assumed they were all controls... so i didn't know what go controlo was... debriefed is the perfect clue for it!! i appreciate the puzzle so much more now
Thanks to @pchow13 for the explanations! I had to read them a couple times (and this was after I stared and stared unfruitfully at the theme entries) so for anyone who wants a blatant spoiler:
Macs use the Command key, while PCs use the Control key for the titular “Shortcuts”. So:
8A: PRINT OST [Mac] = COMMAND-P OST = COMMAND POST
12A: GO OPEN [Mac] = GO COMMAND-O = GO COMMANDO
22A: FIND REAK [PC] = CONTROL-F REAK = CONTROL FREAK
