Gmail - DIV vs BUTTONS - How to invoke CLICK?

I'm trying to FORWARD and email from GMAIL using the WebBrowserControl (C#).

-I am able to open the Gmail INBOX page on the WebBrowserControl...
-I am able to OPEN the specific email (among the others on the inbox) that I need to forward...
-I am able to find and click the FORWARD link to start working with the email fields (TEXTS)...
-I am able to add/insert the email that I would like to send TO...
-I am able to add/edit the content of the email body...

However, now that I am done with the email I CAN'T SEND IT. I need to invoke/click the SEND button but Gmail uses DIV instead of BUTTONS and the regular CLICK does not work.

This is what I did so far. Since most of the DIVs do not have ID, I iterate through all the DIVs inside the Gmail MAIN FRAME (canvas_frame)....

webIE.Document.Window.Frames["canvas_frame"].Document.Body.GetElementsByTagName( "div" );

...and with a regular expression I was able to find the right DIV that contains the text(SEND) that I need to click. Here is the sample on how GMAIL encapsulates the HTML 'SEND' BUTTON = DIV (the same apply to most of the buttons like SAVE NOW, DISCARD, etc).

<div id=":j5" class="J-K-I J-J5-Ji Bq L3" role="button" tabIndex="1" unselectable="on">
    <div class="J-J5-Ji J-K-I-Kv-H" unselectable="on">
        <div class="J-J5-Ji J-K-I-J6-H" unselectable="on">
            <div class="J-K-I-KC" unselectable="on">
                <div class="J-K-I-K9-KP" unselectable="on"> </div>
                <div class="J-K-I-Jz" unselectable="on">Send</div>
            </div>
        </div>
    </div>
</div>

I first tried invoking click ( InvokeMember("click") ) on the inner DIV containing the SEND text:

<div class="J-K-I-Jz" unselectable="on">Send</div>

...but unfortunately did not work, then I tried invoking click on all and any of the DIVs (Parent/Children) of the above HTML code with no luck at all.

Any IDEA/ADVICE on how can I get to SEND the email?

++Thanks
