One of the things that I like about LibreOffice Writer is the ability to bind key combinations to a wide variety of behaviors. This makes it a good word processor for folks used to shortcut-intensive text editors like Emacs or vim. I personally have made extensive use of this feature and have keybindings for navigating and editing text documents almost exclusively from the keyboard.
When navigating via the keyboard, it’s often useful to have the ability to keep the cursor vertically centered in the viewport—in other words to have the document view automatically scroll, such that the cursor always remains vertically centered in the window (in vim, this can be done with the ‘scrolloff’ option). Or, alternatively, it’s nice to have a shortcut key that will re-center the viewport on your cursor at any time (in Emacs, Ctrl-l does this for you; Apple has also introduced this feature in Pages).
It would be nice to introduce one or both of the above options in LibreOffice Writer (i.e., either an option to keep the cursor always centered, or the option to bind a key that will center the cursor on demand). The ability to keep the cursor vertically centered within the text window at all times minimizes the need to use the mouse for scrolling and navigating a document and makes for a much simpler UX for users who navigate primarily from the keyboard.
