Shortcut key to revert to Black & White

[FiestaRed]

I'm sure there is one but I keep getting strange messages when I ask Google. Can anyone please tell me the shortcut I need to reset my colours to Black and White in Photoshop CC?

hover over the icon and it tells you.

Thanks for the help. I'd got it into my head that D was for Deselect but that's Ctrl D.

When you say "Hover over the icon and it tells you" I'm not sure what you mean?

There's a button that does it, hovering the mouse over gives the tooltip
