                            Key Definitions Cheat Sheet


         See SYS$SHARE:TPUINI.TPU for examples of key definitions.  You can 
     also use the CTRL/K command to define keys.  The keys that are already
     defined by the operating system or EDT are shown in the table below,
     including definitions from Kalamazoo customizations, Martin Mariettas
     Computer Services and the standard TPUINI.TPU.  Before re-defining any 
     of them, find out what they do, to see if the function is one you can
     do without, or if some other sequence has the same effect.
