I simply use the keyboard shortcut keys to do most everything in Photoshop. Most people find it faster. To zoom in press Ctrl + spacebar and RMB to select the zoom in area. To zoom out Alt + spacebar + click. For clone tool simply press "S", B= Brush tool, L= Lazzo select tool, M= marquee select tool, P= Pen tool, E=Eraser, spacebar= panning, ctrl + J = copy to new layer, ctrl + T = free Transform tool,  and so on.
