For navigating in man pages, I use the UP and DOWN arrow for scrolling. But it seems that since the update to KDE Applications 15.12.2 it broke for me in Konsole (and Yakuake) with bash as shell. Has someone the same issue? Navigation on line with 'j' & 'k' works, but ain't as intuitive as arrow keys. Not sure about the PAGE UP / DOWN keys, because I don't use them so much, but there is no response either.
What I found so far is that 'less' is used a pager (defined in the environment variable PAGER) for the man pages and is responsible for the actual scrolling. I suspect the update of Yakuake to be the culprit, but I'm not sure. I also tried an empty .bashrc and a .bashrc with only "export PAGER=less" without success.
I create btrfs snapshots before every pacman update, so I can provide quite detailed information on that. But I need some help pointing me in the right direction on what to look for.
