Enhancement #1934043: Right click on item in the Manage items window to open the window to manage it.

One can now bring up the Manage ??? dialog by holding the SHIFT or CTRL key when clicking the button. If you want a particular item then copy the text to the clipboard before opening the editor then pasting it into the search or filter box.
