Symbol for a key?

[Etinarg]

I haven't played any roguelikes yet, that included keys, so I want to ask: What is the common symbol used for a key?

In nethack they're a blue left-paren.  I dunno if I like that, though.

The Male symbol, ASCII charcode 12 on DOS tilesets might work, it kind of looks like a skeleton key.

At the moment I have decided for a yellow " aka gold key. It seems my display system has no access to the extended ASCII symbols. So I can't use code 12.

Thanks for the advice

ADOM uses ] for keys and other tools. It even looks kind of like a key. But I don't think it really matters that much, probably everyone will find enough differences in graphical representations and keypresses that this one little thing does not matter.

Ok. I juts thought I'm going to ask, since almost all my roguelike experience comes from uLarn, Moria and Angband, and none of these had keys. So I didn't know if the might exist a common symbol in other roguelikes.
 
I think I'll start with kind of a table of available symbols and the items that I want to have, and then see what will fit into one group and then gets the same symbol.

" is a universal symbol for grass.
