Hi,

I think there is a solution. Interestingly, you can get that behavior
by *not* clicking *on* the slider, but in the space to the left or right
of the slider postion. (I have to say, it also works by clicking on the
slider on my platform - but that is probably not the case on all
platforms) Here's the description of the SCROOL keyword to WIDGET_SLIDER.

Set the SCROLL keyword to an integer value specifying the number of
integer units the scroll bar should move when the user clicks the left
mouse button inside the slider area (Motif) or on the slider arrows
(Windows), but not on the slider itself. The default on both platforms
is 0.1 x (MAXIMUM - MINIMUM), which is 10% of the slider range.
