Select By Lookup Subtable
=========================

This dialog allows you to select glyphs which undergo a transformation described
in the selected lookup subtable.

There are three variants on how the search behaves:

#. The selection will be set to whatever glyphs match the search criteria
#. The selection will be expanded. Anything that was previously selected will
   remain so, and anything that matches the search criteria will become selected.
#. The selection will be restricted. Only glyphs previously selected will be
   searched, the selection will be restricted to those which match

   So if you want to search for all ligatures containing both "f" and "i"...

   Search for ligatures containing "f" with "<*> Select Results" set

   Then Search for ligatures containing "i" with <*> Restrict Selection" set
