how to kill ctrl d in notepad++

[asterose]

How the HECK do I get rid of ctrl+d in notepad++??  It is a nightmare and has nearly ruined my life, and certainly has cost me many hours of my life.  I tried going to the shortcut mapper, but it does not show up there.

*censored*.

Only way I can think of is if you download the Notepad ++ source code and then find the CTRL + D function and kill it off by commenting out that feature and then compile it and use that for your Notepad++ needs. At the bottom of this list is the source code for download. You will have to be proficient in looking at code to know what your looking at to find it and disable by commenting the section out or remove it, then compile and run the edited version.

it is in the shortcut mapper. It is SCI_SELECTIONDUPLICATE on the Scintilla Commands tab.
