SUMMARY about mouse speed on Sun3 with OW2

Well it is time for a summary regarding my question to the net
about mouse accelleration and open windows on a Sun 3/60.
Many thanks to the people who replied.

BTW: I sent this the other day to requests by accident. Since it has not
     shown up in this discussion group I am now sending correctly,
     I hope ;-)

My original question:

>>Does anybody have a suggestion on how to control the speed of the
>>arrow relative to the speed of the mouse in openwin?
>>We have one system (a 3/60) that is a beast to get the arrow lined up
>>on one character for the purpose of cut and paste.
>>Looks like mouse acceleration needs tweeking.

Most people pointed me to the xset command. I tried it out without
much success. Apparently it is expected to work in OW3.

Good to know responses when we go to OPENWINDOW 3 from:

Stephen Malowany
Peter Shipley uunet!tfs.COM!shipley
Kevin W. Thomas uunet!!kwthomas
Gordon C. Galligher uunet!!gorpong
Michael Meyers michael.meyers@Corp.Sun.Com
Robert Williams
Jonathan Corbet
Doug Becker

Right on responses for OW2 from:

John R. Kilheffer
Greg Earle uunet!poseur.JPL.NASA.GOV!earle

Greg's was most explanatory so I included it here.
Basically he said, use the old editdefaults command that was used
in Sunview and then run input_from_defaults when starting openwin.

Thanks again to everybody who responded.
