For future reference, if you zoom your browser way out (the text might be too small to easily read) the buttons will eventually come into sight. You might want to count the number of times you press the control+minus key combination so that you can press the control+plus combination the same number of times get back to your accustomed zoom level. This will be important if you have custom commands which rely on SetMousePosition.
