Forms in email - clicked link tracking?

Hi everyone

I've been playing around with a form in email (hat tip to this great Email on Acid blog post!)

Here's the code:

<tr>
 <td align="left"><form method="get" action="https://www.gadventures.com/search">
 <input type="text" name="q" placeholder="Where to next?" style="background-color: #eeeeee; border: 0; font-size: 16px; line-height: 22px; padding-left: 4px; color: #2d2d2d; font-family: 'Helvetica Neue', Arial, Helvetica, sans-serif;"/>
 <input type="submit" id="search" value="search" style="display:none;"/>
 </form>
 
 
 </td>
 <td align="right" style="padding: 0 10px;"><label for="search" style="cursor: pointer;"><img src="https://arcdn.net/ActionRocket/Blog-article/search-in-email/search.png" alt="Search" width="39" height="39" style="display:block;"></label></td>
 </tr>‍‍‍‍‍‍‍‍‍‍

Would a click or press of "enter" to search in the email result in a Marketo Clicks Link in Email action? Doesn't look like it does. That makes it tough to evaluate success, although I guess we could just do it via Google Analytics...you do lose all the Munchkin tracking though, which is great for lead scoring.

Any ideas?
