increasing font size on the fly

[martin f krafft]

Hello,

I am a very happy urxvt user, but on the occasion, I have to give
screen presentations and need a terminal with a larger font.
Obviously, I can start a new urxvt process with the -fn option, but
usually I am already half-way through my presentation when the
person in the last row wakes up and demands a larger font, then
I don't want to restart.

I cannot figure out how to change the font size in urxvt on the fly.
Ideally, I'd be able to define 2-3 unicode fonts of different sizes
and have a key combination to toggle between them, but I cannot find
anything in the docs.

Can someone please give me a clue (or state that this is not
possible)?

Thanks,

--

the reason the mainstream is thought of as a stream
is because it is so shallow.
