hebrew (or arabic) transparency to call up when i forget key location?

[Michael Shiloh]

i just found a nice feature in Unity (new to me at least): press and 
hold the "special" key for a semi-transparent overview of keyboard 
shortcuts, great for jogging the memory.

such a transparency of the hebrew (and arabic) keyboard would help me 
learn to type in hebrew, as i have only english letters on my keycaps.

does such a thing exist?

if not, i'd like to make my own: hopefully i can find one already in 
source form and give it the correct properties, then figure out how to 
bind a key to display it.



any thoughts appreciated.
