Report How to emulate control keys only? (LCtrl+RCtrl+RAlt) in General Questions Posted July 16, 2020 I've trying to interface with a MiSTer (FPGA gaming device) and it requires keyboard shortcuts that only contain control keys without any normal keys. For example, one combination is LCtrl + RCtrl + RAlt. However, in the Flirc GUI it requires one normal key in additional to the control keys. Thanks for any help!
