How to do GUI SHIFT + Simultaneously

[Kainen]

I am trying to figure out how to do three buttons simultaneously, specifically GUI SHIFT +. I just got my rubber ducky today, so I am rather new.

What encoder are you using? Using the correct target language when encoding?

Are you talking about this? https://hak5.org/pages/ducky-encoder

That's one encoder, yes. But, the question is if you are using it when encoding a payload containing the key press combo that fails.

I am, however key presses like GUI r, work just fine. I guess what I am asking is how to do something like that but with three "GUI SHIFT +".

I can't seem to remember what that specific key combination ("GUI SHIFT +") is supposed to do, so it's a bit difficult to guess what you are trying to achieve. In any way, the JS encoder has problems encoding some specific/rare key combos, where the Java based encoder is successful with the same payload script/ducky script. Not sure if that is valid in this specific scenario, but it can be tested at least. It seems that Hak5 has removed the Java encoder from the downloads section of the web site ( https://downloads.hak5.org/ducky ), but it's still available on Darren's GitHub.

Another explanation might be that the key combo isn't supported by the keyboard/language files that are used when encoding. In that case, some changes has to be made so that it can be interpreted by the Ducky in a correct way.
