I am trying to put two subscripts at the left and right of a character. For example, something like: _{t} p_{x} where p is in the middle. How do you do this?

None of the mentioned packages would give a good result in this case, because TeX suppresses space around binary operations in subscripts.
A good solution for this particular case seems to be
\documentclass{article}
\usepackage{amsmath,leftidx}
\DeclareMathOperator{\Hom}{Hom}
\begin{document}
\[
\Hom_{K\cap \,\leftidx{_a^b}{\!K}{}}
\]
\end{document}
The \, pushes right the right operand a bit, so to separate it from the intersection symbol. The K would however be too detached from the prescripts, so I add a small correction.
There is no real systematic way of dealing with this, unless you wrap your scripting into macro-form where you can place content in a more consistent way.
Moreover, this is probably not something that happens often, so some manual intervention via \vphantom takes care of the problem:
\documentclass{article}
\begin{document}
$A_{P_{i+1} P'_{i+1} P'_i}$
$A_{P^{\prime}_{i+1} P'_{i+1} P'_i}$
$A_{P^{\vphantom{\prime}}_{i+1} P'_{i+1} P'_i}$
\end{document}
Best Answer
There are many tools for scripts:
For general math scripts before something, use
\prescriptprovided bymathtoolspackage, for better alignment:$ \prescript{14}{2}{\mathbf{C}} $For large operators, use
\sidesetfromamsmath:$ \sideset{_a^b}{'}\sum A_n $For chemical equations, use
mhchempackage:\ce{^{227}_{90}Th+}For tensors, use
tensorpackage:$ M\indices{^a_b^{cd}_e} $$ \tensor[^a_b^c_d]{M}{^a_b^c_d} $Please complete this list as you can.
