    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 \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 \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
