Deck formatting

Anywhere within the file, format the deck that you want the notes to go into as:

{Target Deck Line}
{Deck name}

Or as:

{Target Deck Line}: {Deck name}

For example, with the default settings:

TARGET DECK
Mathematics

Or:

TARGET DECK: Mathematics

You may place more than one target deck in the same file, but only the first instance will be read and used.

Obsidian plugin only

See Folder settings for how to do this on a folder-level
