Using keys other than caps lock as hyper

Is caps lock the only key that can be used with the "act as hyper key" action? I typically use the Tab key as hyper when held, and tab when pressed. I've been trying unsuccessfully to get this working in BTT, but don't know if it's something I'm missing or if it's impossible

If anyone could help me get this working I would greatly appreciate it, since this is one of the only things blocking me from getting rid of Karabiner Elements!

I'm not sure, but probably this kind of remaping only works with carabiner elements.

Have you seen the brand new "hyperkey method" with the trackpad? If you have one...

Otherwise, you might want to try this.

By the way, Key Sequences also work with "tab" as the "modifier". But I don't know if that works reliably, because I don't use it.
