URI scheme

Yahoo! Messenger's installation process automatically installs an extra URI scheme ("protocol") handler into some web browsers, so that URIs beginning "ymsgr:" can open a new Yahoo! Messenger window with specified parameters. This is similar in function to the mailto: URI scheme, which creates a new e-mail message using the system's default mail program. For instance, a web page might include a link like the following in its HTML source to open a window for sending a message to the YIM user notarealuser:

<a href="ymsgr:sendim?notarealuser">Send Message</a>

To specify a message body, the m parameter is used, so that the link location might look like this:

ymsgr:sendim?notarealuser&m=This+is+my+message

Other commands are:

    ymsgr:sendim?yahooid
    ymsgr:addfriend?yahooid
    ymsgr:sendfile?yahooid
    ymsgr:call?yahooid
    ymsgr:callPhone?phonenumber
    ymsgr:chat - opens chat room list
    ymsgr:im - opens the "Send an IM" window
    ymsgr:customstatus?A+custom+status - changes the status message
    ymsgr:getimv?imvname - loads an IMVironment (example: ymsgr:getimv?doodle, ymsgr:getimv?yfighter)
