The source is very small and can be used both through the file:// and hosted http protocols. So you can easily make it do whatever you like. I could maybe expose some global variables to make it customizable, but I went for simplicity and smaller source instead.

if it helps, all you need to do is add this listener to support the cmd key:

`document.addEventListener('keydown', (e) => (e.metaKey && e.code === 'Enter' && evaluate() && e.preventDefault()));`

The metaKey[1] is only accessible for keydown.

Ctrl-Enter is the shortcut for inserting a soft newline for content-editables on Safari btw. You might want to consider supporting command-enter for this reason alone.
