Just had a look at the OPTIONS and it appears that the script indeed has the prefix of "script:"...
Below is the script I copied form within the OPTIONS - Shortcut keys tab. it reads as follows


script: /*! Highlight naked edges */ var gd = moi.geometryDatabase; gd.deselectAll(); var breps = gd.getObjects().getBreps(); for ( var i = 0; i < breps.length; ++i ) breps.item(i).getNakedEdges().setProperty( 'selected', true );


But still throws the said error.

Have tried deleting and re applying the Shortcut, but no luck either.
