Description Tobias Theuer 2020-03-01 00:47:14 UTC
SUMMARY
It is often helpful to scroll to the previous command.
This is especially useful when compiling code that can produce many error messages, but only the first error message message is of interest.
Of course, there are ways to circumvent the need for this, such as piping to less or temporarily disabling the auto scroll feature, e.g. by scrolling up one line.
But all of these workarounds need to be applied before running the command and it's often more convenient to decide after the command has already produced lots of output.
In addition, depending on the way the prompt is formatted, it is often not easy to manually scroll to the last command because it is hard to distinguish the prompt from the program's output.

STEPS TO REPRODUCE


OBSERVED RESULT
Scrolling manually (with the mouse wheel or shift + up-arrow) is slow, distracting, prone to missing the prompt and therefore scrolling too far up,
etc.
Searching for a part of the prompt (by pressing ctrl + shift + f) is the best current solution I know of, but it's also far from ideal.
Remembering to make Konsole not scroll to the next prompt is difficult, annoying and needlessly complicated.

EXPECTED RESULT
It would be cool if there was a quick and simple way to move the viewport to the last command.
This is a feature that would in my opinion help almost all users, from beginners to already experienced users.
Konsole could store a queue of viewport positions, where each command inserts another entry, and positions that are no longer inside the scrollback buffer leave the queue.
A key binding such as ctrl + shift + up arrow could then move the screen to the previous command, and ctrl + shift + down arrow could move the screen to the next command.
As far as I know, this feature is not currently implemented in Konsole, but there are other terminal emulators with this feature.

Did you try Ctrl + Shift + PageUP/PageDown/Home/End ? this all work by default in konsole IIRC. Also you can configure the behaviour of Ctrl + Shift + PageUp/Down to scroll half/full screen in the profile settings.

About making the prompt more distinguished, research "bash prompt color", some interesting stuff.
