Control of Text Fields.

[Richmond]

I did not mean "competing" in the sense of "b*gger you", I meant it in the
sense of healthy competition.

"But having said that:  your "left-arrow' emulation gets it wrong if 
there is a chunk selection active."

Quite possible as I spent about 15 minutes on that yesterday between 
raking up dead leaves,
drilling through the metal head of a broken rake to screw it onto a 
wooden handle, and a whole
slew of other things such as talking to my son in Lilongwe re setting up 
discarded PCs out
there (Malawi) with Xubuntu and a programming suite that has recently 
been effectively abandoned.

I have a sackload of kids writing that has just arrived via Viber that 
has to be addressed:
after which I'll have a look at my "half cock job" and see if I can 
tweak it.

Richmond.
