So, there is no standard behaviour?

Ok, that would solve the problem but has the side effect to break the
autorepeat in all other programs under the same X-server. It is a little
annoying to use editor in that environment.

Thank you so much for your time. These are possible solutions but it may
be that there is no ideal solution. If you ever happen to run into a
XExtraKeyReleaseEventsOffWhileAutoRepeatStaysOn ( ;-) ) function call
when leafing your X11 reference, please drop me a line. I'll try the
AutoRepeatOff command in the meantime.
