Pasting the same thing under multiple items would also be good (like what you want to implement for "add marked item as child") -- we could then copy and paste a small hierarchy of selected items under many items in a second instead of doing it in several minutes.

 

 

Just to make things clear for Wayne as the help file is not up to date for parent-child linking: 

 

1- There's ctrl+drag+drop.

 

2- There's xml copy/paste (selection in the copy dialog) -- if you pick the option to paste as a link to the current parent, you'll have a new children-parent relationship.

 

2- and there's marking : select items, mark them*, select another item and click on the "add marked items as children" (item context menu option)

 

 

 *right click on item: it's a the bottom of the item context menu -- you can create a shortcut for that (I have ctrl+t for selecting, ctrl+alt+t to add items to the current selections, and ctrl+shift+t to add marked items as children of the currently focused item)
