My stuff prints item links in the chat window, I can shift click if I have the blizz AH open and it fills the item name for search, not with the aux search open

I think you can alt-click it? Cant check right now.

Thanks ! Alt click works !!

is it on purpose that it's different than blizz? maybe so one can choose to send it to either?

Actually in vanilla it was right click for both this and container items. Unfortunately this is not possible in classic. For container items shift click is already used so i made it alt for both for consistency. Actually maybe i'll make it work for shift also when i have time to avoid confusion for people used to the blizzard ah.
