Close active window
I know Ctrl+W closes active window. Would it be possible to code in a standard Windows shortcut, Ctrl+F4, for this?
Change the mapping with the Shortcut Mapper?
Settings (menu) -> Shortcut mapper -> Main menu -> Line 12 (Close)
The standard Windows shortcut is Alt+F4, not Ctrl+F4. And Alt+F4 works as expected. If you click the NPP icon in the upper-left of the NPP window, it will pull down the standard Windows “move/size/close” menu, which shows the global shortcut for closing the window is Alt+F4.
