Press T for target, N and P to cycle targets, then W for the single weapon dialogue, then select weapon slot. W dialogue works against the currently selected target.

Sorry, not trying to be dense but I probably am here.

1) Does the W key just work for Tanks? I tried it now with the German heavy infantry that has Mortars and I hit T but then W does nothing.

2) You say what I want is weird. Not sure I understand so maybe I am missing something else here.
