in chapter 2 zooming in and out i learned many different ways. you can hold “z” key to zoom in and command option space bar to zoom out. you can use the icon located on the left tool bar and command 0 to fit the screen.i learned how to change the size of the image by typing the size in the zoom box at the bottom left hand corner.i learned that the space bar give a hand to drag and scroll with also. the “r” key is for rotating the image or the tool on the left hand side may swell. the key “m” changes the cursor to a regular cursor. using the navigator panel shows and lets you zoom and look at certain places in the image closer.i removed the shortcut for spotlight and changed it to a zoom shortcut.
