When a backpack is in a Curio slot and the configured hot key is pressed the backpack inventory will open. That is, of course, the expected behavior except that the hotkey also opens the inventory when typing in a text field such as the filter field of JEI.

Whoops, that is definitely not the supposed to happen. I think I will make it so it doesn't open if another inventory is already open.

I fixed it now in version 1.0.18, if another screen is open the key bind is now ignored.

Thanks for the report!
