What is “Search Plugins”? What is “Search Keywords”?
* Search Plugins: They are plugins that define a search engine within the [Mozilla](http://www.mozilla.org) application framework. They make a search engine appear in search box, usually located on the upper right hand corner of a Mozilla web browser window (Seamonkey or Firefox). They also add functionality to the search sidebar.
* Search Keywords: They are keywords that function as shortcut for search engines. For example: type “google example” in location bar (where you type URLs) will bring a Google search for keyword ‘example’.
Why Search Keywords?
* It is simpler. Simply type the engine keyword (for example ‘google’), followed by space and the keyword you want to search.
* It requires less keystrokes and/or mouseclicks. No need to click on search box, select search engine, and finally type keywords.
* Less clutter on the screen. You can free up screen space used by search box!
* It is simpler to [add your own search keywords](http://www.mozilla.org/docs/end-user/keywords.html), not so with search plugins.
* No more annoying leftover keywords used from previous searches. And no need to clear search box from leftover keywords too!
Why Search Plugins?
* Ordinary users might not be immediately aware of search keywords.
* It is easier. Click on the box and type the keyword. No need to figure out which keyword to use.
* End users can easily add more search plugins simply by [clicking a link](http://mycroft.mozdev.org/top30.html)
* Unlike search keywords, search plugins usually act the same from computer to computer.
* Search sidebar is sometimes very handy.
Which one for me? Neither, because I’m using [Konqueror](http://www.konqueror.org). But there is ‘Web Shortcut’ feature which is very similar to Search Keywords in Mozilla.
