Hello, I do not know if it's the right place to post, pardon me if it isn't. I have FSUIPC4 registered and I am running FSX:SE still (poor me!). I am mostly flying the PMDG 737 and I wondered if there was any way to put a shortcut on items. For instance, what I would like is set a button which would kill or light up the retract lights (not the whole landing lights as you can do with PMDG but only the retractable ones.) I thought I could do that with a mouse macro but it doesn't seem to work. Thanks for helping me, Best regards, Kim.
