10. Zooming the Image

Ctrl = allows you to zoom in, and Ctrl - is zoom out. Ctrl-R displays the working image at 100% (one pixel in image = one pixel onscreen), and Ctrl-Shift-R fits it to the window (normally the correct thing to do). These zoom commands are also all available from the Zoom menu. They do not rescale the underlying image, merely change the magnification with which it is displayed onscreen.
