+These controls are configurable by editing the key.cfg file which will be
+copied to your personal directory for uqm data the first time you start the
+game.
+The location of this directory varies per system.
+On Microsoft Windows systems this is a folder named 'uqm' in the
+application data folder for the current user.
+This is usually in one of the following locations:
+- "C:\Windows\Application Data\"
+  (Windows 95, 98, SE without seperate users)
+- "C:\Windows\Profiles\YourName\Application Data\"
+  (Windows 95/98/SE with seperate users)
+- "C:\Documents and Settings\YourName\Application Data\"
+  (Windows NT/XP)
+On Unix systems this personal uqm data is stored in "~/.uqm".
+Later versions of The Ur-Quan Masters will include a key configuration tool.
