Drawing in MS Word

[Easystreet]

I am trying to use the scribble option in MS Word. I am using this function by clicking on Autoshapes in the draw tool bar. Then clicking on lines in the pop up menu and finally clicking on scribble. The problem I am having is that once I take my finger off the mouse button, if I want to draw another shape using scribble I have to click on the scribble option again. Is it possible to be able to carry on using the scribble option without having to go through this procedure. This option is available for drawing lines, if I double click on the lines box then I can draw as many lines as I want without having to keep clicking on the lines box after I have completed one line.
