Hi Raúl ;),
In the case of C-PgUp, I prefer shift-PgUp for the scrollback
facility, but many systems have Ctrl mapped, instead.
Indeed i use it that way, shift+pag keys for scrollback and control+pag
keys for zsh history functions. This mail is making a new question
arose in my head... ;). It's not related to Zsh, so sorry for the noise
;).
How can the size of the scrollback buffer be incremented? I guess it is
in the kernel console driver, but where? I looked for it some time ago
and didn't find it...
