In SciTE 3.6.0 (Linux version) the shortcut "Control-Shift-D" has been assigned to the new "Search/Selection Add Next" function but this shortcut was already assigned to the "View/End of Line" function, so there is a conflict. It's a very minor problem because it's easy to redefine shortcuts in the SciTEGlobal.properties file.
This should use the same shortcut as on Windows, Ctrl+Shift+9 bt that doesn't work on Linux - checked on current Ubuntu. Ctrl+Shift+N works and isn't likely to be required for other uses.
