Description:
A lot of software use the SHIFT+ENTER shortcut to insert a line break which brings you to next line (e. g. Firefox, Thunderbird, MS Word...). This can be also set in writer using Customize Keyboard using "Insert Manual Row Break" function. But for some reason this is not possible to do in sCalc, which uses a hard command "go to upper cell" (means moving 1 cell up).

This is behavior of LO sCalc forces to remember the specific shortcut CTRL+ENTER in sCalc especially, which is almost impossible, since man works automatically and subconsciously. As I said, all the software I work with uses SHIFT+ENTER to scroll down a line, even in Writer I can set it up. Only sCalc can't. I'm talking about the case where I'm editing a cell directly through F2 (i.e. I'm inside the cell). The strangest thing is that if I edit the cell via the Input line, the SHIFT+ENTER works in the same way as CTRL+ENTER. LibreOffice is great in that it can be customized, so I guess this is some kind of bug.

Steps to Reproduce:
1. Try SHIFT+ENTER inside the cell (F2).
2. Try SHIFT+ENTER in the input line.
3. Try to set keyboard shortcut for SHIFT+ENTER ("Insert row break")


Actual Results:
1. Moving 1 cell up
2. Inserting line break
3. Setting a keyboard shortcut for SHIFT+ENTER ("Insert row break") does nothing. 

Expected Results:
We should be able to set a working "Insert row break" shortcut to SHIFT+ENTER for the purpose of editing a cell (F2) to act the same way as in the Input line (and other SW).


Reproducible: Always

Additional Info:
I tried to set the  "Insert row break" function for another free shortcuts, but without success. It seems the editing of the cell is protected from using user-defined shortcuts. As mentioned, it is confusing that SHIFT+ENTER acts as CTRL+ENTER in the input line.
