My assignment for today, should I decide to accept it (and yes, I know that shows my age...what doesn't?) was to add a Firefox extension.
After much perusal here I found something nice and simple that I could make use of: Google Hot Keys.
Download it to your computer. Call up Google in Firefox and do a search. A little box appears around the first record (up and down arrows move the box). Now a few cool things can happen:
* The extension automatically checks the document and lets you know if it is no longer available on the web. If one of the words you searched for is no longer on the page, the program shows the word in red with a strikethrough.
* Hit the letter P and the screen splits, showing you a preview of the webpage you are currently considering.
* All the words you searched for are highlighted in yellow on the page. My one suggested improvement would be making that optional on any given page, because some become mostly yellow.
