I have appended the @sk labels (the 4 character code i.e.  INSC,DELC,etc)
with a code that  indicates how

the key label code is used or can be detected. Those marked with a "-" are
trapped and used internally by

filePro and cannot be detected. Those marked with an "*",  trigger  @wuk
and can be tested within @wuk

processing. A mark of "b",
