As the title describes, I cannot open the inventory while the SHIFT key is held (I hold SHIFT to sprint).
It doesn't happen with the original AE2

Environment

• Minecraft Version: 1.12.2

Hey there. This is a direct consequence of this mod having a Shift+E bind. I might implement a workaround later on to make it only trigger if you have a terminal.

You can change it to a different key in the meanwhile.
