		Electric presumes that Macintosh mice have 1-button, PC mice have 2, and 
		UNIX mice have 2 or 3 (only 2 are used).
		Therefore, different versions of the mouse commands combine key presses with clicks.
		
		For example, the selection button is used to highlight objects on the display.
		On systems with 1-button mice (i.e. Macintosh),
		the selection button is a plain click of the button, but on systems with two or three buttons,
		the selection button is the left button.
		
		A note to users of the KDE 2.1 window system (Linux/UNIX): The Alt-Left button 
		is used by the window system, and as a result, you may not be able to issue the 
		Special Select button. To disable the window systems use of this button 
		combination, use the KDE control tool, select "Look & Feel", "Window behavior", 
		"Actions" tab. Near the bottom, select "nothing" instead of "default move".
