I've tried your Xy4/Sig system of accessing both lexicons and run into a snag.
Instead of substituting the chosen value under Signature, I get a menu that
says: bort <s>tore <n>ext <q>uit. About all I can do is quit. The toggle is
still valuable because I can make a mental note of the choices. But it would be
better if XyWrite made them for me when I hit the enter or replace key. Other
than that, everything works fine, including the toggle program which I use as a
"lex" macro. Any thoughts would be appreciated.
