Hi Graeme,
Awesome tools! Specially really like that new diff feature you added. Will be tremendously useful. I also am following a convention like this to label my hotkeyed letters:
"|&Set diff region", "xset_diff_region", "","","";
"Compare |&Diff region", "xcompare_diff_region", "","","";
"|&Beautify project", "xbeautify_project", "","","";
