At the moment, the only thing I can think of is that edit_lines take a block
which is triggered when text is added to the contents. I've not tried this,
but I suppose if a tab character is inserted, the block could remove it and
shift focus to the next edit_line. Then that could shift focus on a tab to
a submit button, and a keypress block might be able to pick up a return
there, subject to the interaction of these keypress and edit_line facilities
operating together nicely.
I think one could then type
32946<tab>Fred Bloggs<tab><enter>
to fill in both fields and submit. But this is only running correctly
in my head, which even I wouldn't recommend as a platform for serious
computation!
What do you think?
