The Ctrl+Tab used when TabManager has focus has always allowed the user to step through tabs. I will check if Next Tab is registered for use by the shortcut menu.

Update: checked the code and Next Tab and Previous Tab are both registered with the Shortcut Manager so you control those shortcuts.

As for Shift Tab or BackTab that should go back to the previous place you tabbed away from. The QTabBars do now allow focus by tab so that tabs inside Sigil Preferences can now be accessed from by Tab shifting focus as previously there was no easy keyboard way to change tabs. Using the arrow keys on a QTabBar should allow you to change to another tab.
