-- How to use this script:
-- 1. Install the Logitech Gaming Software: http://support.logitech.com/en_us/software/lgs
-- 2. Launch it, and click on the small arrow on the profile (Default uses gear icon) and then click on "Scripting".
-- 3. Add the following code into the Script window, save it, and close it.
-- 4. Unassign the keys in the GUI otherwise both the binding below as well as the GUI assignment will be sent.
-- Now G13 is bound to F13, G14 to G14, ... G18 to F18.
-- 5. If you'd like to use the GUI instead, now it's easy to create a "Command" with F13-F18

function OnEvent(event, arg)

  -- OutputLogMessage("event = %s, arg = %s\n", event, arg)
