Subject: Detecting Special Keys (@sk)

In clerk, filePro lets us inspect and act on special keys when we leave a
field
using @wlf, or if the special keys: DPRT, GRAF, INSL, DELL are enterd,
when updating a field via @wuk

Besides the 4 special keys triggered by @wuk, there are several special keys
that do not cause us to leave a field, such as LTAB, RTAB, CLEF, etc that
and have not other effect than to put the cursor at the beginning of the
current
field.

Is ther any way to detect these while in a field?  If not it would be very
high on
my wish list.

John

Yes, there is a way but it is sort of a pain in the neck.
It involves the use of waitkey in @wef processing.
If you have access to old copies of the filePro Cookbook, there is an
article that I wrote in one of them (John?) called "@wel - When Entering
Limbo".  It gives you a detailed explanation of detecting just about any key
(except the "end" key) from within @wef processing.  I use this quite a bit.
It is very powerful.
