You can use a variety of language keyboards within a LockDown Browser exam.
Step 1: In Windows, navigate to: Control Panel->Clock, Language and Region-> Change Keyboards
Step 2: Select “Change Keyboards” and then add your desired keyboards.
Step 3: Now that you’ve selected your keyboard, click on the “Advanced Key Settings” tab.
You’ll likely see that no key sequences exist for your designated keyboards. Highlight the desired keyboard, then click on the “Change Key Sequence” button.
Step 4: Select a key sequence for each keyboard you desire to use in LockDown Browser. For this example, the English keyboard will have CTRL+1 designated.
The Russian keyboard will have CTRL+2 designated
Step 5: Apply your keyboards and Key Sequences
Once you are in LockDown Browser, you can use those key sequences “on the fly” to switch back and forth between keyboard languages.
