If you type x^\Uparrow you get $x^\Uparrow$ which is not as clear as $\Uparrow$. (It could be my monitor's low resolution.)

    $\begingroup$ Which is to say x^{\Large \Uparrow} and x^{\large \Uparrow} and x^{\Uparrow} $\endgroup$ – Peter Phipps Jun 1 '13 at 23:02
  • $\begingroup$ @Peter, one would hope they'll right-click on the $\LaTeX$ expressions to figure out how it was done... ;) $\endgroup$ – J. M. isn't a mathematician Jun 2 '13 at 4:15

    $\begingroup$ @J.M.: personally I would prefer $x^{\displaystyle \Uparrow}$ instead if one wants to override the implicit \scriptstyle that makes the arrows smaller. $\endgroup$ – Willie Wong Jun 3 '13 at 8:47
  • $\begingroup$ @Ｊ.M. I had no idea you could do that :O $\endgroup$ – Emily Jun 4 '13 at 19:08
  • $\begingroup$ @Willie, fair point. :) $\endgroup$ – J. M. isn't a mathematician Jun 4 '13 at 19:10
