"*Must* fix"?  Really?  Its just 13 methods!  They're the very first
methods I ever wrote for Squeak back in January 2002, and have used
heavily ever since.  If the VM won't be fixed can't we just find
another fix for the deselection bug?

This widget provides a specific set of low-level gestures optimized
for list pruning, which is what traceMessages needs.  If you go
"cleaning it up" and reducing it to a lowest-common-denominator
functionality, there really could be some woofing and barking around
here.   :)   Ha ha, no seriously, if you feel the need to clean it,
lets please review the usage cases, there are very good reasons I took
the trouble to write that instead of using the original..
