Consider this approach:
- Go to the source block.
- Press a desired key combination.
- Register the shortcut as in Right Sidebar & Keyboard Shortcuts
- And as in File picker for linking local files, the handler should:
- form
[](((the-uuid-of-the-block)))
- It could also fill the text part with something relevant.
- place it in the clipboard
- form
- Paste it where you want.
- Fill-in the text part if it’s not already filled in step 2.
