Nothing @ Niko exactly, but I saw a couple posts about this on my way down. For selling all greays with one click I just use the following macro. Other usefull dumb macros like this can be found out on the "interweb"


/run local c,i,n,v=0;for b=0,4 do for s=1,GetContainerNumSlots(b)do i={GetContainerItemInfo(b,s)}n=i[7]if n and string.find(n,"9d9d9d")then v={GetItemInfo(n)}q=i[2]c=c+v[11]*q;UseContainerItem(b,s)print(n,q)end;end;end;print(GetCoinText(c))

I use a gray sell macro. However, there's one thing to be careful of. Running many sell macro just "uses" the item. If you have a vendor window up, then "using" the gray item sells it. But if not, then using an item like a gray sword will equip it without you realizing it. Even worst, you may wind up selling your primary equipment thinking it's a loot. So in my macro, I put in a vendor check such as:

if GetMerchantNumItems()>0 then... end

It checks the number of items the vendor has for sale if you have a vendor window up, which will typically be at least one. Otherwise, a zero means no vendor window is up, and the macro is halted. It's not perfect, but it does the job 99.9% of the time. The other 0.1% of the time, you'll run across a vendor that has NO items for sale, and you'll wonder what's going on.
