From the description on CompuServe:

TKEY.COM - TKEY is for all those people with Tandy 1000's that are tired of 
hitting the PRINT key when you were aiming for the '\' key.  In fact Tkey 
will move the '\' key to F12 and say memory resident.  I have tested it and 
found that it works with everything except Macro programs.  K Macy
