A couple of ways to make text size larger when there is no desktop icon to do so...

One way:
- Right click on an empty portion of the desktop
- From the pop-up menu select "screen resolution"
- Select a LOWER resolution for LARGER text

Another way:
- If the attached mouse has a scroll wheel, roll it up while
- holding the CONTROL key down

- To make the text smaller, do the reverse - roll the scroll wheel toward you while pressing the control key

And yet another:
Check to see where the slide bar in the lower right of Microsoft Word and other programs is set... Should be in the middle for best application of font size changes, but can also be "slid" back and forth to make the page larger or smaller.
