Shifting a symbol vertically in Math mode

Question

I have a small nitpicking query

I have:

$S\sqsubset\mathbf{P}$

and noticed that the \sqsubset symbol is a bit too low (off centered) for my liking. Is it possible to shift it up slightly?

Answer 1

You can redefine \sqsubset to take an optional argument that would raise it:

\documentclass{article}
\usepackage{amsfonts}% http://ctan.org/pkg/amsfonts
\let\oldsqsubset\sqsubset
\renewcommand{\sqsubset}[1][0pt]{%
  \mathrel{\raisebox{#1}{$\oldsqsubset$}}%
}
\begin{document}
$S\sqsubset\mathbf{P} \quad S\sqsubset[5pt]\mathbf{P} \quad S\sqsubset[1pt]\mathbf{P}$
\end{document}

The updated \sqsubset is set as a binary relation \mathrel. Note that if you want to use square brackets after \sqsubset, you need to surround it with braces. The new usage is \sqsubset[<len>] where <len> is any recognized (La)TeX length.
