Hi Tony,

Thank you very much for your explanations. Since I am using console
vim most of the time I am trying to get it working there.

The result of the test is, that vim doesn't see any of the keypresses.
You wrote that is due to the terminal.

I dont understand this completly I fear...

The zsh, running under the same terminal adn which was the one startet
vim, does see ALT-nackspace.

What I am doing/inderstanding wrong here?

Best regards,
mcc
