Comment 4 for bug 1276776

Orson,
Be careful when using Alt+Fx
Most of time they are filtered by the D.O.S. + Window manager.

In Kicad, a zoom command can be Alt+Fx (x = 1,2) or Fy (y= 1,2,3,4).
for F1 and F2, they are a bit different.
F1 and F2 execute a zoom change + zoom center on the current mouse cursor position.
Alt+F2 and Alt+F2 execute only a zoom change because (obviously) they are mainly commands coming from the main menu, and the mouse cursor position is irrelevant.

F3 redraw the screen, and F4 center the screen to the cursor.
But Alt+F4 closes the current screen on Windows..., and cannot be used instead of F4.
