Tex symbols

[HiPPiE]

Hmm... I'm writing a paper and trying to figure out how to make an x-vector symbol.. as in:
\beq ds^2=d(\overrightarrow{x})^2+dt^2 \eeq
Except with a smaller arrow over the x, as would be seen in a real paper.

perhaps $\vec{x}$? that gives you the standard vector arrow if you like that ;)

ds^2=d(\overrightarrow{x})^2+dt^2

ds^2=d(\vec{x})^2+dt^2
