Blender documentation could mention the shortkey Ctrl-Alt-Numpad0...
"Align Camera to View" shows Ctrl-Alt-Numpad0
Otherwise, one might accidentally (unknowingly) be moving their camera unintentionally when working with more than 1 camera.
I thought this was a bug until I realized what was happening. The change of the active camera works with Ctrl-Numpad0, but the unintentional keypress with "alt" may occur, not realizing that it actually altered the position of the active camera.
