DED on the VC404 (COPS10) Terminals


The function keys have the following meanings:

pf1	word right
pf2	word left
pf3	word erase (ie erase the word under the cursor)
pf4	word rubout (ie erase the previous word)
pf5	cursor down
pf6	tail erase ( erase the line after the cursor)
pf7	character erase (erase the character under the cursor)
pf8
pf9	head erase (erase the line up to and including the cursor)
pf10
pf11	special (see DED documentation)
pf12	change mode (see DED documentation)

the arrow keys have their appropriate meaning

For detailed info on DED commands see the documentation in %s/ded/ded.1

Most of the function key assignments were in the original DED and were meant 
for a terminal with different key layout (ITT terminal I think). There are a 
few obvious problems: the word left and right functions are the wrong way 
around; and the cursor down key is in an awkward place.

Another problem with DED is that it has very limited global edit facilities.
In fact it is not possible to globally replace one string by another in one
command. Instead you have to step through the text to each occurence of
your  string and change each one individually. For this purpose the
normal editor is preferable. However for entering documents where you often want 
to  correct an error noticed on the line above DED is great.
