- * PWKeys V1.0
- * By Preben Nielsen
- *
- * PWKeys is an input-handler that allows you to manipulate windows
- * and screens by pressing keys on the keyboard (a lot faster than
- * using the mouse).
- *
- * Once installed, the program only uses 1124 bytes of memory. To
- * remove PWKeys simply run the it again.
- *
- * NOTE: There's no need to 'RUN' or 'RUNBACK' this program from the
- * CLI. It terminates immediately.
- *
- *HISTORY
- * Made with Hisoft V2.12
- *
- * V1.0 20-Apr-91: This is first release. I made it over a year ago
