I've used auctionator classic fixed for 2 years in tbc+vanilla, but in SoM it has errors, so I downloaded the
auctionator that works in SoM. When doing the two things I always do to save time, it appears to not function.
So I have to manually write the product I am looking for, especially in enchanting or leather-working tab, when you need materials.

It does for me. Can I get a screenshot of how you're trying to do it?

Which two things are they? Using Shift+Click to search for an item when the Shopping tab is open works, and when the AH is open a search button appears in the crafting panel to search for all the reagents:

I actually dont have that search button there, but the issue is if you were to shift+mouse1 click the "bolt of linen cloth" image, it doesnt paste it directly in to the search area

so 1) mouse over Strange Dust 2) hold shift 3) click mouse1 4) nothing happens
same thing with the shopping TAB

1. Have you restarted WoW since installing the new version of Auctionator?
2. It looks like a bug is preventing the Shift+Click from working, if restarting the client doesn't fix the issue, can you installing BugGrabber (retail version works) + BugSack and tell me what error they report?

yeah, give me a minute or two

I installed them, tried again, but didnt get any notification from bugsack that I can see

OK. I think the bug is a Blizzard change - I tried disabling Auctionator and it still wouldn't let the Shift+Click shortcut work (I setup a SoM character with enchanting to test). I'll do some digging to try and find a workaround.

Oddly, Shift+Click on the dust adds a link to chat and shift+clicking an item in your bag searches for it.

nice, hopefully you find a solution for it! 👍

yeah it definitely seems to be a SoM thing, I've never had this issue in classic tbc/retail before

I've added a fix for this to the newest alpha
Auctionator-9.2.18-5-ga98fca4-classic.zip
