Description matthies 2008-09-30 22:02:05 UTC

Please provide a keyboard shortcut in tree views to move the focus to the parent node. For example Backspace (prior 
art: Windows tree controls). There's already Cursor-Left that does move the focus to the parent node, but only if the 
current node is collapsed or is a leaf node. This means that Cursor-Left cannot be used to move up from an expanded 
node without collapsing that node. In particular there's no efficient way to use the keyboard to move several levels up 
in a tree view without modifying the expansion state of the traversed nodes.
