Changing title, description and keywords

Where do I change the title, description and keywords? Couldn't find anything in the FAQ's.

Cheers,

Jason.

Products and Categories can be customized individually by clicking on the Black icon on the right ... when customized it will change to orange ...

The default meta tags are set in the language file:
/includes/languages/english/meta_tags.php

This you copy to your templates and overrides directory:
/includes/languages/english/your_template_dir/meta_tags.php

Then, when there is not a default set ... the meta tags are dynamically built utilizing your defines and building from the page that they are on ...

This is done with the file:
/includes/modules/meta_tags.php

This usually does not need any modification, but if you do, utilize your templates and overrides directory:
/includes/modules/your_template_dir/meta_tags.php

ok. I have no idea what you just stated above but I need to know.

I thought that the meta title is automatically read, showing in the title bar when categories and product pages are being clicked on.

I figured out how to change my home page title bar...but now no matter what page you go to, the same title bar is shown.

All of my little circles are orange but still no changes. I also made sure that in the layout section of admin, I have all meta tags set at true.What am I doing wrong?

Is it possible to have each title show?
If my category is kid's gifts and the product is teddy bear: If I am on the teddy bear page, can it state in the browser bar; kid's gifts teddy bear or will it just state teddy bear?

Maybe I should be more clear. I know how to get the meta tag file but you stated that if no default, the info will be taken from the pages...

What about the the home page? I customized the title, keywords for my home page. I don't want them to show for every page.

I want a different title bar for each page. How can I obtain that?

When you say not a default set, you do mean that the mega tag file must be empty in the define title and define keyword sections?

Also, in the modules/metatag ; the meta_tag_over_ride is set to false.... is this correct or do I need to change that?
