I bought a laptop (Lenovo 14" 2-in-1) with the purpose of drawing in Photoshop. The pen that came with my computuer works as a brush/ eraser just fine, bu the touch gestures for zooming, undo, redo, aren't working. It is very inconvenient because I would like to draw with my laptop in tablet mods and i cannot access my keyboard to use those shortcuts there. How do I fix this?
