Alright, it’s been frustrating me for over a few months now, I’ve researched a lot and finally decided to ask for help.
Since a few months ago the CTRL + 1, CTRL + 2, CTRL + 3 & CTRL + 4 shortcuts don’t work for me anymore. I press them but nothing happens. I must’ve done something wrong… It broke on both of my pc’s which have roblox studio installed.
They seem to work for me on version 0.477.5.421956 (64bit), could you attempt to reinstall Roblox Studio?
If that doesn’t help, then it’s probably time for a bug report, but the Post Approval queue stopped in September 2020 and Devrelations team didn’t find a good alternative yet.
