I haven't yet thought about doing it from within coz there seems to be
no attempt !?? I've sometimes used the list format, then set filter to
CATEGORIES and get SUMMARY|DTSTART|DTEND - but then I get the result
window on a "per-event" basis (so no further export possible, eg. to
handle it in spreadsheet applications) ?!! So what I'd need is an export
on a record-similar basis and an export format that other applications
can handle ...

The local calendar is the only one :-)

That's what I did so far, but as the list gets too long (more than 20
entries I guess) I can neither see it in ONE SCREEN nor PRINT it in any
way nor export it somehow :-((

Sorry, Milan, but what I'm looking for is a "quick & dirty" solution for
my home use, no time to get into C programming :-(
Any inspirations for existing tools (no GUI needed) to handle the ICS
format ?
