Allegro IDE - entering characters important in Lisp

Hi All,

I wonder how one inserts a Backslash or At-Sign from Allegros =
IDE-Editor.

If I press then Backslash key (Alt Gr =DF on german keyboard) the IDE =
responds

"There is no selected object in the selected window to pass to =
MACROEXPAND-COMMAND"

If I press @ (Alt Gr q on german keyboard) a window

"Process(es) for Bug Report Backtrace" opens.

I find this weird. Can I change this behaviour? How do I insert a =
Backslash or At-Sign from my german keyboard (german system)?


Thanks for any hint.

Andreas
