Windows has (for programs that follow it of course) good tab management shortcuts. Ctrl pgup/pgdown to go left/right (equivalent to MacOS's shortcut mentioned above), and ctrl+tab to cycle through historical tab order (which many Mac programs have as well IIRC).

But for me the nicest shortcuts in windows are Win+# for applications. Win 1, 2, 3, etc. to select a program in that slot on your taskbar regardless of whether it's already open, and holding Windows and cycling through that number's windows, along with your standard alt tab for all windows in historical order. That, combined with the non-centered taskbar icons means you get great muscle memory on both keyboard and mouse, better than Mac OS's dock IMO.

Of course, MS is doing its best to kill this for some reason by insisting on limiting how you position the taskbar, trying to center everything, and randomly sticking "Search" into the taskbar periodically. Also for whatever reason sometimes the keyboard shortcuts are not reliable in Windows 11 lol.

I can't say I like all of Microsoft's plans, but the fundamentals are there, and they were solidly designed at some point.
