Does anyone know a shortcut for discarding/removing/deleting a Layer Mask in PS7? I haven't found it anywhere.

I don't think there is one. But you could always make an action to make your own hotkeys. I have a pretty extensive .pdf list of PS7 hotkeys. If anyone wants it, send me an e-mail.

Hotkey! Of course Ed, why didn't I think of that? :dizzy:

Alt (or Mac: Option) + drag to Trash avoids the annoying confirmation message.

Shift+click on the layer mask to deactivate it temporarly.

The right-click on the layer mask thumbnail, then choosing the correct option works fast for me, there is no confirmation...
