Will take a look, thanks.

It's part of a syntax checker/corrector for the Maple language.  A
tool (mint, analogous to lint) generates a buffer of the variables
that are undeclared in the source.  I grab the list and allow the user
to either quote them in the source or declare them as locals or
globals.  Being able to delete selected items from the list allows
performing a common operation on the remaining.  The typical case is
that almost all the variables should be quoted, but a few should be
declared as locals.
