Russian mnemonic keyboard three letters missing: щ ч э

You just need to type multiple keys to get to those letters: For example some (not all) of them:

sh -> ш

ch -> ч

jo -> ё

je -> э

And this is just awesome. This means you just type the way it sounds and Russian letters just magically produced.

Chego eschjo xhelat'? -> Чего ещё желать?

Note that the left hand side is quite readable as is.

It is nice that windows 8 added a mnemonic Russian keyboard.

Unfortunately there are three letters which I can not find: щ, ч and э.

These three letters exist in the standard Russian keyboard. They are at the following location (in the US  keyboard): o,x and '.

Without these three letters the mnemonic keyboard is useless

One not very obvious aspect is the way the combination "ые" is typed, by the way. You actually need to hit the spacebar after typing [English] 'y', so that the keyboard knows you are in fact typing 'ы' and not the first element of ’э', which is entered using the English key sequence 'ye'. By contrast, if you want to type 'ые’ (as in 'красивые') you need to type '[krasiv]y[spacebar]e.'

Was frustrating for me before I figured that one out...
