Reset shortcut keys for Calc

Hello Libreoffice users,
Thank you for your valuable help in the past. I Have a new problem now.

The CTLR+SHIFT+ENTER Array formula combination is not working for me.
I try to find where I can set that key. I could not find something like “Enter Array Formula” in keyboard customization settings in Libre Calc.
Somewhere I read that those keys assigned in Ubuntu, are not assigned in Libreoffice.

How can I re-set the Array enter formula combination;?
Where I can set that combination?

Sincerely,
Elias Tsolis

As a workaround use the Function Wizard Array check box.
