I create prototypes for TV using a Flirc device to enable us to test with a remote control that is mapped to keyboard keys using your key/gamepad option in the interaction details panel.

The ability to long-press a key on the remote is a key interaction for us and the addition of a drop-down menu to enable the long-press of certain keys (amongst other options) would be greatly appreciated!

I have created a mock-up of one way that this could work… but would welcome any way to achieve what I have described above!
