accessibility

I accidentally pressed some buttons while starting Word 2013, and I don't know what I did:

I purchased a Chromebook for an elderly relative to use. I've enabled every helpful accessibility feature (large cursor, cursor indicators, etc).

I would like to adjust the styling of websites on a specific domain in Firefox, but the instructions I found

In Visio 2007, the "Shapes" window (the stencil) shows the master icons and their text labels. Is there any way to increase the font size used in that window?

I am currently modifying some values in the Mousekeys registry under HKCU:\Control Panel\Accessibility using PowerShell.

Is it possible to change text cursor color systemwide? I want to make it easy to catch red color.

I have a tagged PDF that has a one remaining accessibility problem: some background images were never tagged as background images.

I have updated my google-chrome to version 57 , after that menu font size and tabs font size and bookmark bar font size , are very large. and I hate that. So I try to fix it,but I can't.

This is what I'm kind of looking for, but it only works in the terminal.

I run the 3d application Blender and the program has the ability to do it's own desktop space on each screen of a multi monitor setup.
