gnome3 wallpapaer with keyboard shortcuts

[wilifo]

Though I'm not quite a first time gnome3 user, I'm still not sure about the most useful keyboard shortcuts, and I would love to find a wallpaper with a description of the main ones. That would save me the headache to memorize them
Wonder if someone could help me on that.
Thanks

I don't know if any currently exist, but if you install the Gimp, then it would be no trouble whatsoever to knock your own together using whatever image you liked behind it.

Thanks Roxoff, your suggestion would certainly work.
I haven't yet used Gimp and I'm not aware of those shortcuts, but after some research it would not be too hard to get the job done.
Will engage myself on that in case no one else mention something the like, already ready to use.
