Scroll Up - does not technically scroll up, it (if anything) scrolls down. Will need to be renamed in next big update & will be a breaking change.

Scroll Up is used internally but exposed as a public method on IConsole. As new functionality is being added to Konsole, allowing for ViewPorts and scrolling in all directions, this needs to be reviewed. In the next big release, this change will probably be rolled up into a set up viewport and "true" scrolling functionalities, where you will be able to scroll Up (to see previously written text, i.e. the History that has since scrolled off the top of the screen.)

This probably will not impact any users of Konsole, but in case someone is using it, please note that after the next big release, you'll need to use ScrollDown, not scrollUp.

For the definition of Scroll Up, or Scroll down, please see this explanation here: https://www.webopedia.com/TERM/S/scroll.html

Konsole will be using the term ScrollUp in future to mean, you want the display to shown one or more lines towards to the top of the Document you are viewing. So the text moves down, and "older text" that was not visible should become visible at the top.

Scrolling Down will mean the reverse.

And lastly, when you're writing to the end of a screen and it causes the text to overflow the existing screen, then the screen (or buffer) will be expanded by 1 line, if you are already at the bottom of the screen or window, and the UI will then Scroll Down 1 line. (All the text moves UP 1 line), the new line will be filled with the default fill character, and window (console) colors.
