Hi,
If you're using an external keyboard, you might have to use the fn key in conjunction with the F-keys, or iOS will intercept the F key and perform the special functions such as change the volume, brightness, etc.
If you're using Remoter with no external keyboard. Simply press the button labelled "F" on the special keys toolbar (the toolbar above the keyboard).
Thanks,
Raf.
