On most terminals, once you get to the end and you've typed the last
digit, the cursor flashes a little differently, and you're in a mode where
you need to press a field-exit (or similar key) before you can continue.
Hitting LEFT/Backspace should put you back to the spot where you can
change the last digit of the field. The cursor doesn't actually move, it
just blinks differently. :)

Can you elaborate on what's wrong with FIELD+? If it happened in the last
few weeks, its probably my fault. :( What does it do wrong?

Just above where you added the K_ENTER there is some code that says
something like:
case K_LEFT:
case K_BACKSPACE:
tn5250_display_indicator_clear (This, TN5250_DISPLAY_IND_FER);
return;
Try adding some code below that which looks like this:
case K_UP:
case K_DOWN:
case K_RIGHT:
tn5250_display_indicator_clear (This, TN5250_DISPLAY_IND_FER);
break;
(note the "break" instead of "return" will cause it to move up/down/right
as well as clearing FER)
Is that what you're looking for? (I'd get up and try it on a terminal,
but I've just spent too much time with tn5250 today, already)
