How it works on Gnome (since "shell"/3.x IIRC):
* Super + Alt + up/down to switch workspaces
* Super + Alt + Shift + up/down to move the current window to a different workspace
* Super + left click to drag windows
* Super + left/right to resize to half screen
* Super + up/down to maximize/restore
* Drag a window to the left or right edge to resize it to that half of the screen.
