Support for single-line scrolling (enabled by option "Scroll single line using Shift-Up/-Down keys" in Edit->Preferences->General) was removed. Why? I used it frequently. If it is dangerous or the shortcuts are needed in shell commands, it can be just disabled by default. Please give it back! Reproducible: Always
the last ebuilds are identical, see: x11-terms/xfce4-terminal$ meld xfce4-terminal-0.8.7* Changes could be in the upstream source. Please ask, there and add a link to your ticket here.
Thank you for your very quick reply. I found that Ctrl-Shift-Up/-Down can be used instead. This report is in vain then, sorry.
