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.
This feature is supported in every other mindmapping, charting tool, so it’s an easy copy from those tools.
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
