How to FC an app may vary depending on your Android version and device.

If your Android device is using virutal keys, like Nexus devices, you should swipe up from the bottom to display the keys. Otherwise most often you just select "multiple app" button, which is a square on Android 5.0+. After that all running apps are listed and swipe away RR3.

For older devices or other ROMs, the multiple app button is not available and that is a menu button, you may need to long press home button to display running apps. Or just Google your ROM and find it out.
