1.  Tcemp will simulate the buttons used by xemp by the fol-
lowing keys:

     * Space - Left button
     * Tab - Middle button
     * Return - Right button

The Message window will show you what each button does,  but
generally speaking you could say that:

     Space always views the sector

     Tab always does a cancel
     Return always activates the command.
