After separately copying the 4 shortcut code lines from the Documentation PDF, to Notepad++, and removing the CR and/or LF (Carriage Return, Line Feed), at the ends each code line, by backspacing, I have reached the following conclusion:

The Documentation PDF shortcut code contains several CR and/or LF, which if copied to the shortcut key, cause the shortcut code to fail.
I would suggest changing the PDF to not create CR and/or LF, (if possible), OR add a text file of the shortcut code, to the NodeEditorPlus zip file, and tell the user NOT to copy/paste original PDF code.

Edit: CR and/or LF can be removed in Notepad++, (find and replace), per internet searches.

I am now done with this shortcut topic :-)
