I am using LibreOffice Version 7.6.4.1 (AARCH64) on a MAC desktop (Apple M1 chip)running macOS Sonoma 14.1.2.

My problem is inserting an equation with an equation number.

when I press the fn + F3 key on my keyboad, it does not open the equation editor. I get the error message “AutoText for Shortcut not found”. Hoe do I rectify this problem ?
