Zooming window to reveal free transform handles
When you free transform (Command+T) a layer, you often find yourself zooming out loads so you can reveal the handles on the edge of the bounding boxaround the edge of the layer. This is especially hassle when its a large layer on a small canvas size.
You can auto zoom the view to fit the bounding box around the layer you are transforming by hitting Command+0 (number 0). Nice and simple, one to remember!
