I am looking for this symbol:


I recently discovered it in a paper. However, I was not able to find it in the "Comprehensive List" (symbols-a4.pdf) or anywhere else.

Have a look at “How to look up a symbol?” for ideas how you can easily find a particular symbol. – Martin Schröder Sep 29 '12 at 23:33
I tried all of the steps mentioned there, but thanks anyways. – user1658887 Sep 29 '12 at 23:49

I've never seen this symbol, but you can easily build one very similar. This is my approach in text mode: MWE



\textbackslash{\tt arrowdot~~~} \arrowdot

\textbackslash{\tt arrowdotdot} \arrowdotdot

Subway \arrowdot Airport \arrowdotdot Railway

Looks great! This gives me an idea on how to achieve it. Thanks! – user1658887 Sep 29 '12 at 23:49

You can also use the usual overkill option of tikz which then gives you all the flexibility inherent in tikz. Here are a few of the possible options where you can easily control the location of the dot (pos=<percent>), arrow length (x=<length>), arrow type, and color:

Further Enhancements

  • If desired this could be enhanced to provide separate draw options for the arrow and the dot.



\newcommand{\arrowdot}[1][]{% #1 = optional draw paramaters (applies to both arrow and dot)
        \tikz [x=0.75cm, y=\heightof{\strut}, line width=.2ex, ->, baseline, #1] 
            \draw (0,0.4) -- (1,0.4) 
            node [pos=0.4,shape=circle, fill=black, draw, inner sep=1pt, #1] {};

    $A \arrowdot B$

    $A \arrowdot[pos=0.5, -latex, x=1.2cm] B$

    $A \arrowdot[pos=0.6,red,->] B$

    $A \arrowdot[pos=0.2,blue, -stealth] B$

I tried dtexify and it did not work in this case. – user1658887 Sep 30 '12 at 17:11

The chemfig manual have also an interesting example of arrows with dots:



% Example from chemfig manual, page 58
% http://mirrors.ctan.org/macros/generic/chemfig/chemfig_doc_en.pdf

\edef\pt@radius{\ifx\@empty#4\@empty 2pt\else #4\fi}% dot radius

A \arrow{-.>} B \arrow{-.>[above][below][][1pt]} C \arrow{-.>[][below]}[30] D \arrow{-.>[above][][5pt][1.5pt]} E
