>Description:
Some of us prefer the h-j-k-l vi mantra from traditional arrow keys. It would
be very convenient to have those keys work in scrollback history buffer. I am
submitting a patch to enable j-k keys for up and down, and u-d for page up and
page down -- works much faster to browse the history screens now.
