My thanks to @JimRac for letting me know that there are discussions in the community here about using AutoHotkey to automate tasks in Scrivener. I only just discovered AutoHotkey, which I used to automate the Edit > Text Tidying > Remove Empty Lines Between Paragraphs function.
I wrote a script for AutoHotkey as a workaround because Scrivener for Windows does not work when using the keyboard shortcut for this function and does not allow us to assign it a shortcut. I solved the problem with my script and, to make it even more helpful, assigned the AutoHotkey to an Elgato Stream Deck button.
