Google Talk Command Line Options

Turns out Google Talk hooks into the operating system to give you some command line options, which means you can create desktop shortcut icons that link to specific Google Talk actions. As Ionut Alex reports, using “gtalk:chat?jid=[Gmail-Username]@gmail.com” will launch a Gtalk chat window for the specified contact, while “gtalk:call?jid=[Gmail-Username]@gmail.com” will automatically call that person.
What you can do with this is create a shortcut, on your desktop, that launches exactly the chat or call option you are interested in, and you can even create an icon for it (like a picture of that person’s face). You can also use this in conjunction with Windows Task Scheduler, to make Windows automatically call a specific person at a specific time, which opens up all sorts of possibilities (including practical jokes).
