Enhancement Request, or how to construction line

I find myself over and over changing lines to constructionafter I create them.

It would be great if I could hold a key while creating a line whichcauses it to be construction, sort of like holding the alt ondimension creation to disable the snap.

Either that or just a command to create a construction line which Ican shortcut to.

Please correct me if there is already a way to create aconstruction line in one shot.

Thanks.SolidworksSketching
