How to run a Google Desktop search from the old Google Deskbar

I've found the solution to run a Google Desktop search from the old (and much more functional) Google Deskbar. The instructions can be found here, but here is the gist of it (in case that page disappears):

Copy your Google security token, stored in the registry at:

HKEY_CURRENT_USER\Software\Google\Google Desktop\API\search_url

In Google Deskbar Options, add a new custom search. Paste the value of the above key, adding {1} at the end (including the brackets, no space). The resulting query URL should look something like this:

http://127.0.0.1:4664/search&s=MyDha7HlPkadS4etveAys9zzjJI?q={1}
