Updated an unknown developer's old "Cancel All Auctions" macro (basically by just adding in a "break"). Obeys the requirements of one-hardware-action-per-cancel, doesn't cancel auctions with bids (or try to cancel already sold auctions), doesn't require any specific auction addon, *does NOT check for underbids*. Open up your auction tab and just keep punching the macro 'til they're all canceled. Enjoy.
/run local o="owner" p=GetNumAuctionItems(o) for i=1,p do local _,_,c,_,_,_,_,_,_,b,_,_=GetAuctionItemInfo(o,i) if((c>0)and(b==0))then CancelAuction(i) break end end
