Typography of Mixed Tensor Index Notation

How can one properly and quickly write a mixed "tensor" such as $$\Gamma{}_{1}{}^{2}{}_{3}$$?

Shortcuts such as esc Gamma esc, Ctrl+^, Ctrl+_ are prefered. I intendd to use this in an inline equation in a Mathematica Text cell.

• I've seen Mathematica output looking like that, so I know it is possible. I just don't know how to properly type it. – Miladiouss Jan 14 '19 at 5:10
