Don't you mean "my cooperating version ..."; surely the use-list is 
about helpful cooperatin and collaborative suggestions, not about 
competing :-)


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

left-arrow should position the iBeam to the left of the selection, while 
this code positions it to the left of the rightmost character of the 
selection.
