If you have played with Help in CTP, you would have noticed that there Help Favorites has a node called “Searches”. However, it is not discoverable how to store a search. At least, Kevin was not able to find it.You can save a search by

1. Performing a search.
2. With Search window focused, click on "Add to Favorites” button on the Web/Help toolbar. This is left of web url textbox. This will add your search to the Favorites.
3. You can now click on the stored search to re-execute a search.

We know that it is not discoverable and we will fix it soon by adding a “Save Search” button (not in the next CTP though). This button will exist next to “Restore Defaults” and “Help Options” commands.
