Allan,
thanks for the quick reply. The additional keyboard shortcuts are very helpful. How do you type the alt-Symbol, btw?
I know that switching to a different keyboard layout would work -- but as long as I don't have a keyboard with OLED/digital ink displays on each key I am not certain I would handle it as well ;)
As for services: I use [Service Scrubber](http://http:// www.macupdate.com/info.php/id/20192) to trim my services and change shortcuts. Apple's interface would work as well -- but somehow seems less appropriate for this case.
