Is your feature request related to a problem? Please describe.

When posting large amount of auctions that get undercut quite often, it's a PITA to manually click it.

Describe the solution you'd like

I would love to see something similar to TSM's keybind post/cancel. Like shift + scrollUp or something.

Describe alternatives you've considered

I only use TSM for this, but it's a bloated AddOn and has a lot of taint issues which is why I would love to go back to auctionator.

Already in Auctionator. You can use [Space] to post when on the Selling tab, and [Space] to cancel when on the Cancelling tab after an undercut scan.

You can pick different keyboard/mouse shortcuts in the settings
