Hello,
Sorry to hear you are having issues. But, the default hotkeys work on my system. Does it not work on yours? The default "Ctrl + Numpad 1" slide out the tiles bar (make it active) and "Ctrl+Alt+Arrow keys" changes the pages. If it don't work on your system. It might because those hotkeys is conflicting with other software hotkeys?
Thanks
