Laptop Dell Vostro 3550

Hi spv1979,

Try using the "Alt" key located on the left hand side of the keyboard and check if the shortcut keys "Alt+=" work. I would also suggest, opening two web pages and check if both left and right "Alt + Tab" key combinations work for toggling between pages.

I hope this helps

Please let us know in case of any queries.

Thanks and regards
