When we're looking at a program, one of the things we often wonder is what the keys for a certain file are. We've written a small utility that we use from the command line window in SEU (you can get this by pressing F21). When you run the command DSPKEY, it shows the keys for the file on the message line (See 4). The source for the command and the programs it uses is in5, 6, and 7.
