Andreas, On windows platform try to use the E12 function key. In the old day's (20-series) this key had the same function. Good luck.

There is no way to use the software or hardware Annunciator keyboard. I could think on a FBM input and a block which sets the FBM-Horn-Output to false but there may be a better solution.
