How to customize ignored word in spelling check using regular expression?

[E81kfzuIkvPU]

I want to exclude any word inside \cite{ } from the spelling check. However, right now, I need to add each word - \cite{blabla} manually. Is there a way to fix this issue?

spell checking can’t currently be controlled by regular expressions, no, but what you want to do could maybe be controlled by the spelling_selector setting, depending on whether the contents of the curly brackets after \cite in your LaTeX syntax definition are scoped differently or not.
