can shift hold be enabled in hal?

[Neil Short]

I have to type one-handed. I wish to hit the shift key so the next letter I type is upper case and the next is lower case. Here is my current x11-input.fdi

<?xml version="1.0" encoding="ISO-8859-1"?>
 <deviceinfo version="0.2">
  <device>
   <match key="info.capabilities" contains="input.keyboard">
    <merge key="input.x11_options.XkbLayout" type="string">us</merge>
    <merge key="input.x11_options.XkbVariant" type="string">dvorak-r</merge>
   </match>
  </device>
 </deviceinfo>
