f12 magnifying lens help

[Skunk Worx]

Hi,

It seems to me in past days I've seen OS's with a magnifier ... like a 
magnifying glass. Move it over something and it zooms that spot "in place".

Sometimes when I go to a web site with very small fonts or drawings I 
would like to have such a tool to move around the page and magnify things.

My default f12 install has a package called "gnome-mag". From what I 
have read on the web it is used/enabled by :

1) System->Preferences->Assistive Technologies dialog
2) Enable Assistive Technologies
3) Select through Preferred Applications-Accessibility-Visual-"Orca with 
Magnifier"
4) Enable Orca "run at start"
5) Restart

But the magnifier seems a little clumsy--it takes over a static area of 
a screen and tracks what is under the cursor, so I have to constantly 
look to the cursor, then back to the magnifier, and back again as I read 
through a page or diagrams.

I was hoping for something like a magnifying glass I could move around 
the screen, perhaps with a control like a SpinBox or a ScrollBar to 
adjust the magnification.

Is anything like this available for f12?

I can always stop by rite-aid and buy one for $2.99 or something :-)

Thanks,
John
