At my employer we typically like to add a reference in the code, to the ticket-id for which a particular code-change was made. It is often required to lookup the request for a ticket-id that we happen to come across in the code.
To make my task easier, I integrated the request system with Google Deskbar. Now to open the request with Id 205 for example, all I need to do is go to the Deskbar that sits in the Windows Taskbar, type 205 and hit Control-R. Deskbar opens request 205 in IE. This offers a great, non-flow-breaking and non-distracting way to quickly look up the request corresponding to a particular Id.
I have also configured Google Deskbar to search CPAN for Perl modules when I hit Control-M and fire a search at Investopedia.com when I hit Control-F.
