I am looking for a way to create a symbol of an arrow in which it points in a downward direction but do not know if one already exist. I have tried detexify to come up with nothing.

The picture of the arrow is below:

See "Table 110: mathabx Arrows" of mirrors.ctan.org/info/symbols/comprehensive/symbols-a4.pdf . If you manage to turn the symbol \Rsh by 90° to the right you've got your symbol. – N.N. Jul 18 '11 at 21:54

Using TikZ you can define a command that will give you a stretchable symbol; you can do something like this:


  \raisebox{-0.5cm}{\begin{tikzpicture}\draw (0,0) -- (#1,0); \draw[->] (#1,0) -- (#1,-0.5);\end{tikzpicture}}}

  x^n + y^n = z^n.

  a= b + c + d + e + f.

Thanks man. This really helped out a lot. I don't use tikz much so I would not have thought of doing it this way. +1 answer. – night owl Jul 19 '11 at 3:12
@ Gonzalo: Thanks again. It works like a charm and the best part about this solution is that it is easy to maintain, i.e., make adjustments to fit your ones particular needs with some minor changes. Thanks Again. :) Gotta learn this tikz package to draw things. I have inkscape, but have not done much with it yet. – night owl Jul 19 '11 at 22:18

This might be what you are looking for:



Try $X\rRsh Y$ and make your comments.

If mathabx is loaded instead of amssymb, the same definition produces a symbol with two equal segments.

To get an extensible horizontal bar, define

  \makebox[#1]{\leaders\hrule height 1.25ex depth -1.16ex\relax

and then \longrRsh{3cm} will produce a 3cm long symbol (the figures are optimized for the amssymb version).

@ egreg:Thanks! It worked very well. Could you add a little extension on the the already good answer to show how to extend the arrow longer to the right? – night owl Jul 18 '11 at 22:40
Not quite what I meant, but I see the difference in the suggestion stated above. I wanted the segment that does not have the arrow tip connected to it to stretch across the page to a certain spot to point down right over a set of equations. – night owl Jul 18 '11 at 22:49

This is not quite what you are looking for but might be good enough:

    a \rhookdownarrow b

Thanks for the response, I might find that symbol helpful later. But not quite what I was needing at the moment. – night owl Jul 18 '11 at 22:36
