Since the only manufacturer of display adapters that seems to agree with my
ideas of what a screen font should look like is IBM, I of course do use
setfont to select something that is acceptable. But I remember hearing
that Linux is capable of working with multiple selectable character sets.
Are you saying that this selection is not made by character set name? From
what I heard, I sort of got the impression that there was a variable
somewhere that corresponded to that name. Am I that far off, and if not,
how can I access that variable? I am pretty sure that the font that I am
using is some variation of ISO 8859/1, but I have never checked the
details.

Well switching to another console entirely defeats the utility of the
command that I want to implement. My usage is that I am reading through a
text document, and I come to a juicy morsal that I want to grab - ZAP! to
the printer. Switching consoles breaks the train of thought.
But how can I bind a key to a script without having it print on the screen?
Or really the question is "How do you do a TSR program in Linux?" Thanks
for any guidance here.
