CI Users Guide - Links Read are not highlighted, Why?

[eluser]Unknown[/eluser]
My very first day of reading about CI. One of the very basic things I look for is, does the software track where I have been ( when I want it to) ? I am reading Help on my local machine and on ellislab. My browser Firefox, does not track visited links. Why?

I have not seen any buttons like next or prior, would these buttons be difficult to put in the Help?

Just means there isn't any CSS rule to mark a different color for visited links. You could edit it yourself if you really wanted it. The user guide is a reference, though, not a walk-through, so it's not really something that's important or necessary.

Thanks, I am planning on reading all the general topics. RTFM

Where do I figure out where and why this would be done on a CI site?

view source shows
var CSS_PATH = xxx/resource/css/a-list/web/resources/css

actual path is
xxx\application\views\themes\a-list\web\resources\addons

I understand whats going on here in the .htacess

RewriteCond $1 !^(index\.php|images|assets|uploads|robots\.txt|css)
RewriteRule ^(.*)$ index.php?/$1 [L]

I have no idea what you're asking.
