As stated in the question: is it possible to enable back-cycling through open applications when using alt-tab? Eg., pressing alt-tab goes one app forward, and pressing alt-shift-tab goes one app backward?
I just encountered an issue related to this in elementaryOS 6 (Odin). The
Alt+Shift shortcut for switching keyboard layouts was interfering with the default
Alt+Shift+Tab shortcut for cycling backwards in the window switcher.
