[ Before posting bugs, please check
https://code.google.com/p/hackerskeyboard/wiki/FrequentlyAskedQuestions and
the existing bugs for known issues - my responses may be delayed since I
have very little time to work on this project. ]

What steps will reproduce the problem?
1.Open Connection to Windows from RDP client
2.Alt+Shift or Ctrl+Shift not change language
3.

What is the expected behavior? What do you see instead?
I wrote about the desired behavior in Issue 458.
But maybe it makes sense to implement these combinations through your own 
"compose" key

What version of Hacker's Keyboard are you using, for example "1.37"? (See
"Debug" section at the bottom of the app's Settings menu.)
1.37.1419
On what phone or tablet?
"Samsung galaxy note 2"
If applicable, does this affect the 4-row or 5-row layout, or both? Which
language(s)?
5 row, Russian, English
Please provide any additional information below.
It would be good to implement these key combinations in both ways. But those 
people who often use their Android device for remote access to the PC will be 
glad to any decision. Remote access is very inconvenient to switch between 
languages using the mouse. This operation is often needed for those who have 
more than one language on their PCs.
