Since I can remember in Microsoft Excel (and other spreadsheet applications) one can use “Screen lock” keyboard key to change the behaviour of the arrow keys. If you turn it on you can scroll the entire window (you don’t have to use the mouse and scroll bar) instead of just changing the current cell.
You can see the behaviour explained here with a short movie:
Also in Wikipedia you can find this entry.
I was searching the Internet how to enable it in LibreOffice, but could only found the Bug 46200 - “[RFE] Use the Scroll Lock key as a toggling lock key like Excel” on the Libreoffice’s Bugzilla page from 2012. Also on Apache OpenOffice (AOO) Bugzilla we have the similar Issue 7179 from 2002(!). Both “bugs” are actually not been processed since beginning.
I think that most probably this basic functionality was actually never working in Open/LibreOffice Calc and should be considered as an Feature Request. Is there any way that it will be targeted as a new feature for future releases?
