Normally you have a speed description in the Script itself
script: /* Show objects, or isolate */ var objs = moi.geometryDatabase.getObjects(); var any_hidden = false; for ( var i = 0; i < objs.length && !any_hidden; ++i ) { any_hidden = objs.item(i).hidden; } if ( any_hidden ) { objs.setProperty( 'hidden', false ); } else { for ( var i = 0; i < objs.length; ++i ) { var obj = objs.item(i); if ( !obj.selected ) obj.hidden = true; } }

If it's a direct function you can write
rebuild /*for rebuild a curve*/
