The situation has been improved in latest beta release. Finally, it is possible to easily enter the pipe character (|). Once Karmic Koala final is released (and I got time to install it), I will close this bug when automatic detection of the Apple keyboard type is working. Also, in that case, the remaining issues will be copied to a new or existing bug report with general Apple keyboard issues.
