Avoiding some pitfalls
Though we can use OpenOffice to edit Rich Text files, after trying on
a few different machines I've found that Konqueror doesn't know how to
recognize OpenOffice's native formats: *.sxw for word processing and
*.sxc for spreadsheets. If you right-click on one of these formats,
Konqueror thinks that it's a *ZIP file. Not to worry! If you've got a
big presentation at the office tomorrow and you absolutely need to
make changes to that spreadsheet with the quarterly totals, have no
fear. Simply use the 'Open With' option in Konqueror and navigate
through the menu until you find OpenOffice like so:

You can make your changes and again you'll be prompted to send them over
the network.
