Re: New start up splash screen annoyance...

[Richard Stallman]

            I have a vertical mouse, bought when I was worried about the
     effect of long hours on my wrist.  The mouse sits upright, with all the
     buttons on the right hand side (you can also get left handed vertical
     mice).  The correct names would be "Top", "middle", "scroll", "Bottom"
     and "Thumb" for the buttons on this mouse.

I think it is ok to say that anyone using such an unusual mouse has
the responsibility to know how to translate the usual button names for
it.

            I have a number of mice where the number of buttons is neither 2
     nor three; and the left most button is not button 1.

I am curious what they do; but again I think that we need not concern
ourselves with whether tooltips are correct for such strange devices.

The two-button mouse is the main issue.  That is a common case,
so it is important.
