If you mean that you assign "Q" to "Quick circle" as a short cut, thats jsut one file called moi.ini (I know you knew) So thats one of my extra steps is I keep a text doc in this folder with just the "key assignments" that way when a new beta comes out, I dont have to worry about a different ini file format being ruined by a straight overwrite, I just copy and paste the "add-in" commands only. So my text file looks like this:

Shift+S=SineWave
Ctrl+P=ConstraintPolyline
Ctrl+Q=QuickCircle
Alt+C=CSec
Alt+D=CustomDistance
Alt+G=SpurGearProfile
Alt+R=RingCircle
Alt+P=Pipe2
Alt+T=SelectByType
Alt+S=ScaleArray
Ctrl+A=script:moi.geometryDatabase.selectAll();
Ctrl+Alt+P=script:var img = moi.view.screenshot( 'viewpanel', false ); var name = img.getSaveFileName(); if ( name != '' ) img.save( name );
Ctrl+Alt+S=script:moi.geometryDatabase.getObjects().getSolids().setProperty( 'selected', true );

Easy to just paste this into any ini file for instant custom short assign.

Surely having this integrated will be nice and after the beta and development there will be no issue with changing ini files so a simple 1 file save or move will be easy and probably integrated somehow.

Thanks for indulging!
