[TxMt] Dead Keys Broken

[Garrett Lancaster]

In the latest alpha, my dead keys (set up with Ukelele: 
http://scripts.sil.org/cms/scripts/page.php?site_id=nrsi&id=ukelele) 
produce a snippet completion dialogue and have therefore been rendered 
unusable.

This is problematic because it means not only can the dead keys not be 
used for their alternate purpose, but they can't even be used to insert 
the unaltered character.

Best,
Garrett
