In Firefox, you can associate keywords to your Bookmarks.
For example, you can associate the keyword otn to the main page of JDeveloper on OTN: http://www.oracle.com/technology/products/jdev/index.html
by filling in the Keyword field in the bookmark's Properties:

Typing otn in the Location bar (that you can access quickly by pressing CTRL+L) will bring you to that page.
You can define various keywords, f.ex. to access your favorite blogs
Keyword
| URL
|
| Duncan | http://groundside.com/blog/DuncanMills.php |
Frank
| http://www.orablogs.com/fnimphius/
|
| Steve | http://radio.weblogs.com/0118231/ |
Didier
| http://blogs.oracle.com/Didier/
|

There are also some keywords defined by default as
wp for Wikipedia - see the full list [
Here]
But the most powerful is that your bookmark's URL can include parameters
%s They will be replaced by the words you type in after the keyword.
For example
wp JDeveloper will bring you to
http://en.wikipedia.org/wiki/Special:Search?search=JDeveloper (http://en.wikipedia.org/wiki/Special:Search?search=%s with %s replaced by JDeveloper)
If you have a Metalink account you can define some useful keywords/bookmarks pairs like:
Keyword
| URL
|
Note
| https://metalink.oracle.com/metalink/plsql/ml2_documents.showDocument?p_database_id=NOT&p_id=%s |
Bug
| https://metalink.oracle.com/metalink/plsql/showdoc?db=Bug&id=%s
|
...
| ...
|
With these pairs defined on your bookmarks, typing
Note 395980.1 in the Location bar, f.ex., will display the Metalink Note 395980.1 directly
; and
Bug 5615982 will bring you to that bug reference.
