Shortcout for a paragraph style

You can only apply Paragraph and Character Styles Shortcuts with numbers, a number pad is  handy for this.

And it has to be with a combination with the CMD key, like CMD1

You can add other keys with this CMD OPT SHIFT 1 for example, or CMD OPT 1

As you’re on a MacBook Pro – the numberpad keys are usually hit with a FN and I think the number keys are in the letters, jkl iop, or something like that.

I’m not a Mac user – I’m sure a Mac user would be be more descriptive in getting this to work for you.
