hi, not sure what you mean with 'pick with mouse'. i have simply added 'russian layout' to my exisiting standard UK keyboard and you can toggle between language lay-outs. but sure you have to remember the location of where which symbol now is (under the 'latin' keys) - but with a little practise sort of becomes 2nd nature...(though i did struggle a little with this too, as up to now all my russian teaching endeavours were sort of cursive hand-written
