Found a work around for those stuck on the gun training part of Gemini Rue due to the ctrl key issue:
1. Open the game menu by pressing back button
2. Press "keyboard" button.
3. reassign breathe action to the '6' key
4. Resume the game and you can now perform breathe by pressing the 'f' key on the on screen keyboard.
I stumbled upon this by accident and have no idea why it works but it does on my Galaxy S3. I don't know if it works on other phones.
