edit convert wireframe to composite curve does not have a shortcut, however you can create your own.we will use ctrl+f1 for the wireframe to composite curve command. go to - tools customise select edit from the menu dropdown tick the ctrl box select f1 from the key dropdown and hit the create buttonyou should now see the form like so this will remain permanent until it is changed or you use the remove option on the form. have a go at creating one to turn on the cross hair cursordid you know you could also create a composite curve in on click?
