According to the Scrivener manual for Windows (I hope thatās correct, Iām a Mac user) youāll find the setting via Tools ā Options⦠ā Corrections: āFix capitalization of sentencesā. And maybe also (donāt) āCapitalize āiāā.
Scrivner should NEVER start out with autocorrect capitalizing the letters after a punctuation mark. I say this because it is a writerās program. Writers write dialogue. You donāt capitalize the letter following the dialogue.
Actually, itās more complicated than that. If the line of dialogue is followed by a dialogue tag, then thereās no capital letter:
āWatch out!ā he shouted.
But if itās an ordinary sentence, it should be capitalized.
He shouted, āWatch out!ā The men in the boat couldnāt hear him, though.
And of course writers, even fiction writers, write a lot of things that arenāt dialogue as well.
In any case, in Mac Scrivener youāll find the option in the Settings ā Corrections pane.
