Sounds like they changed how the program is windowed. Ctrl-tab gets you between sub windows in an app, like alt-tab moves you between apps. Shifting in either one of those moves you “backwards” ie right to left instead of left to right. So I don’t think they could really “deprecate” it since that’s a windows command. But if they’re no longer running the UIs as 2 separate windows within the app then ctrl-tab wouldn’t do anything. And then you seem to have found a bug in the app losing its place when you remove focus with the ctrl-shift-I (which is their command).
Don’t get me started on ubuntu.
The upgrade route is Discover.
No way to stop it.
It’ll pester you 4 times a day to let it upgrade a browser lets say.
You do that and 3 days later its pestering AGAIN
Hate it
