Many people would like to delete parentless nodes without having to resort to using the tree, since the parentless-nodes tree view must be reopened after each node deletion. Parentless nodes can be easily deleted using the keyboard only:

• Ctrl-Shft-Up brings up a list of parentless nodes
• after selecting the WikiWord to delete from the list, Ctrl-D deletes the WikiWord
• repeat as needed, no mouse intervention required!
