title: Android keyboard issue
body: <p>This is a question re the android SIP (that's what we call it on WP7).  Please see the clip at <a href="https://dl.dropbox.com/u/39662979/AndroidEmulator.png" rel="nofollow">https://dl.dropbox.com/u/39662979/AndroidEmulator.png</a>.</p>
  
  <p>This is a demo app in the commonsware book on android development.  It displays textboxes for longitude and latitude and shows a keyboard allowing the digits 0 - 9. * and # to be entered.  Of course longitude often requires a negative number but how does one type the minus sign??  I've tried all of the other keys - I'm able to bring up other character sets but no minus sign.</p>
  
  <p>The book shows a minus sign being entered but eluding me.
  thanks,
  Dean</p>
