I found several answers already but all of them are focused on changing size for good, i.e. at Lilo/Grub level. I don't want this though.
So, key issues:
changing size on-fly, I would like to increase size, and 5 minutes later, decrease it back
it is question about text console, not terminal running in X11
openSUSE 11.4 if this matters. Thank you in advance.
I am only interested in size of the font, not in typeface of it.
