    Re: tikz

    Arrow specifications have the form start arrow kind-end arrow kind. To produce a two-headed arrow, set end arrow kind to be >>. To produce $\displaystyle \hookrightarrow$, set start arrow kind to be right hook (the TikZ hook is slightly bigger the standard LaTeX one). Setting start arrow kind to to reversed gives $\displaystyle \rightarrowtail$. All arrow tips are described in section 15.3.4 and chapter 23 of the TikZ manual.

    Example:

    Code:
    \begin{tikzpicture}
    \clip (-1,-2) rectangle (3,1);
    \draw[right hook->>] (0,0) -- (1,0);
    \draw[to reversed->] (0,-1) -- (1,-1);
    \end{tikzpicture}
    Thanks from vernal

    Vernal,

    How did you get the image in your post?

    It seems a good way to post complex and graphical symbols
