Add a to-define shortcut to copy array as markdown

### Describe feature When I try to copy array from Trillium to another page, it lost its consistency and paste each field one under another. But when I exported the page into a file, I got a Markdown array (which was what I wanted). So I wonder if it's not possible to let the user define into settings a shortcut to copy an array as Markdown directly. I think that define by default the shortcut isn't a good idea as the default copy and paste comportment can be usefull for other kind of use case. I'm open to discuss around this idea, and feel free to ask anything :) ### Additional Information _No response_
