The key binding for moving an application to the workspace to the left or right does not appear to work. Shift + Super + Left / Right is listed as the appropriate binding in my settings -> keyboard -> shortcuts -> workspaces but it does not appear to work. How can I fix this?
I just posted this question in case others had the same problem as me. Here is what I discovered.
The problem stems from SuperShiftLeft and SuperShiftRight already being assigned as shortcuts. Install dconf-editor and navigate to org > gnome > desktop > wm > keybindings. From this you will see that move-to-workspace-left/right is assign both SuperShiftLeft/Right and SuperAltLeft/Right. If you want to utilise the Shift option, then delete the assignments for move-to-monitor-left and move-to-monitor-right as it also uses the same keybinding. I assume these assignments were to move windows between multiple monitors, so if you have more than one monitor set up perhaps delete SuperShiftLeft and SuperShiftRight from the keybindings for move-to-workspace-left and move-to-workspace-right, leaving SuperAltLeft/Right as your navigation options.
The SUPER key plus any number key works for me on Luna. However, a second workspace needs to have an application open before a third becomes possible. The SUPER key plus down arrow reveals all open workspaces at the bottom of the screen, allowing one to choose between them with a mouse click if desired.
