Hi, the PluggableAlternateMultiSelectionListSpec is a move toward a
more windows-like operation of a multi-select list. The standard
PluggableMultiSelectionListSpec does not allow rapid swipes of ranges,
nor does it allow using the Shift modifier to do range-selection.
The only reason Alternate has not yet completely replaced the legacy
in Squeak is because we have not yet found a way to allow
Control+selection to not bring up the halos.
Ha! I wonder if, in Pharo, it would actually work because doesn't
Pharo pretty much hide the halos now?
Currently, Alternate is only used for one tool in Squeak
(MessageTrace) and that tool does not exist in Pharo. So, probably
you could omit it, but I would suggest, if possible, to at least
consider omitting the *other* legacy one,
PluggableMultiSelectionListSpec, because I hope that it will be
replaced by Alternate someday (and renamed to take its place).
Whichever is easier..
