@ Psygorn Sorry for the delay!

Say I have clicked on my list of functions of the custom UI the Extend Edges Selection (Alphabetical sorted)
For me it's more easy than to learn hundred of shortcuts for my old brain!
So
I have just to click one edge then Right Click for recall the last function used (so here the Extend Edges Selection) ;)

with this box of filleted edges or any volumes for any edges selection wanted for any reason...

Remarks :) Same result if you click a liittle filleted edge!
you can select several edges in the same time!!! And on several VOLUMES in the same time!!!



PS The Loop selection don't work for this case!
script:/*Loop selection*/moi.geometryDatabase.selectLoop();
