$\rightsquigarrow$ produces a funny looking arrow that points to the right.
I want to get an arrow of the same style but points to the left.
One would think that
$\leftsquigarrow$ will do the job, but LaTex saids it is an Undefined control sequence.
Am I missing something here? How do you get an arrow like
$\rightsquigarrow$ but points to the left?
