I have just written a new post on SDN describimg how to create a bookmarklet to create a set of links to a number of SAP Notes. I also created a bookmarklet to navigate to an SAP Note if you know its number.
You can find the post here.
There is also a file containing the bookmarklets in links so they are easier to add to your bookmarks or favorites. Copying text and making sure it is all on the same line is a little tedious.
Note about SAP Notes: you will of course need a SAP Marketplace login to be able to access them.
