I am trying to use a Knoppix CD to access my files locked on my computer during a NTFS-related error. I have downloaded an ISO and I have burned the CD successfully and Knoppix loads like a dream.

However, Knoppix's default font is so huge that I can't navigate the system. I'm a moderate computer nerd; though I am brand-new to Knoppix, I could easily and confidently follow the instructions I have if only I could read the words on the Knoppix screen!

Can anyone offer any easily-understood, step-by-step directions for how to shrink the text size? I have been Googling forever, but I haven't come up with anything I can understand.

Are you talking about screen size (which can be enlarged, or reduced)
You can move your mouse to the edge of the screen and reduce and enlarge the screen size.
I got this from here, and I don't use knoppix. But I couldn't find anything on Text or font enlargement
