How to activate ABAP?

[peterlangner]

Dear all,

I was positive surprised when I saw, that an abap4.lang file exists and would like to activate it.

I added the following line to the ribbon.xml file:

I deleted the keytip property as it seems not in use and other languages are not having it too.

When I start OneNote I can see the ABAP-Button:

But the language definition was not used to do the highlighting. Is there another config file where I can association the language definition with the button? Or the filename abap4.lang?

Who knows how to do it?

Thank you for your help in advance

Peter
