@godsho First of Alt-D is actually Focus Address Field, so if you're already typing in it then it should do nothing. I'd recommend Ctrl-A (Select all) for what you actually wanted to do. But you did press Alt+key and not just tap Alt, so it shouldn't have displayed the menu even if it considered the combination meaningless. I'll have to see if I can duplicate the issue here; if I can I'll file an issue on the bug tracker about it.
