If you use Google Toolbar on MSIE (not yet on FireFox 3.x from my setup) you will notice some custom buttons.
In the screenshot below, you see BBC RSS feeds in the toolbar.
E.g. you will have a key for
HKEY_CURRENT_USER\Software\Google\Google Toolbar\4.0\Options\Custom Buttons\U_s94057670.onlinehome.us_LJEM2YKD9LEAOCSW86YU.xml
for a physical file called.
C:\Documents and Settings\MY_USER_LOGIN\Local Settings\Application Data\Google\Custom Buttons\s94057670.onlinehome.us_LJEM2YKD9LEAOCSW86YU.xml
For CNN’s feed, the definition is at:
http://edition.cnn.com/browsers/widget/cnn_gtb.xml
which in turns points to:
http://www.cnn.com/browsers/widget/cnn_bn_button_feed.xml
for the data feed.
You can hack around only about 2 RSS variables; search method & feed menu, which is enough for my RSS hacks & tests.
Nothing much but at least you can customize your own buttons if your favourite is not available in Google Custom Gallery.
For more advance hacks… learn from examples !
