Can I configure the controls when playing flightgear on my notebook PC? I don't have a numeric keypad, and have to hold the 'Function' button down for most of the controls. I want to customise it to keep using the same keys, but without holding down the 'Function' button.Thanks.

In your Flightgear data folder there is a file called keyboard.xml; you can edit it to change they keybindings.
