How to change your text size in Vista?

I am trying to enlarge the text size on my web pages.

For example, most web sites have very small print. I will then use a zoom feature which will allow me to increase the text size, however, I then must go back and reset it to 100% when I get back to my yahoo home page since the print is too large for the page.


How can I increase the text size on web pages without going back and forth with increasing and decreasing the text size.

What I have tried-

1-I have increased the DPI, however that only increased the sizeof the icons and such.

2- Went under view and text size and set it up at largest.

3- Went under tools- internet options- advanced- and checked what I thought could help solve this issue.


Thanks and I am not computer savvy!

I have Vista and my browser is IE

 

I use the Ctrl key and the mouse scroll wheel to alter text size

 

Thanks, I just tried that and I could not get that to work. I do have a lap top if that matters.
Thanks
