PromptParams › spellcheckMode?

Type: SpellcheckMode

The mode deciding whether the input is spell-checked.

The default is what this modal has always done, so passing nothing changes nothing: the input follows Editor > Spellcheck, like Obsidian's own name-entry surfaces. Pass SpellcheckMode.Off for a box that is really a search field, or SpellcheckMode.AlwaysOn to spell-check it whatever the vault setting says.
