Faster way to add card in canvas

Use case or problem

It would be really nice if we could create a new card with a keyboard shortcuts. Just an unconnected new card at the beginning would be enough but later it would nice to add relative to a connected cards e.g. new sibling, new parent, new child cards.

Proposed solution

This feature is supported in every other mindmapping, charting tool, so it’s an easy copy from those tools.
Proposed solution:
While a card is selected but not being edited the following key would do the following commands.
Enter - create a sibling card
Ctrl + Enter - create a child card
Shift + Enter - create a parent card
