Anyone knows where can I find a virtual cyrilic keyboard? or how to change it in windows??
On Windows, there's a way to add different keyboard layouts to a list so you can switch between them instantly with button combinations like "ctrl+shift+1" or "ctrl+shift+2". I use it a lot.
On Windows 7, you go to Control Panel>Region and Language>Keyboards and Languages>Change keyboards.
Then add whatever languages you want to the list, and then go to "Advanced Key Settings" to give them hotkeys.
One other option is to use Google Translate: https://translate.google.com/
I'm not sure what pops up for you, but you want "Russian" selected for the input box on the left. When you do that the input box should have a microphone icon and a keyboard icon. If you click the keyboard icon it should bring up a little virtual keyboard with the Cyrillic alphabet. This is what I have been using!
