Hello, 

You can do it by the artifact action menu on the right side from artifact checkbox, in which you can select "Edit Attributes..." and then window with all of the artifact attributes will appear. Select Artifact Type and change it to the required value. 

 Hello Venkat,

If you only need to edit one Artifact Type, double click the Content to make it in edit mode (or use the pencil), then a pull down option appears to the left next to where all your rich text and paragraph editing options appear at the top of your columns.  It will show the current artifact type that is selected.  From the pull down menu, the artifact types that you set up as your preferred types for the module will appear with their little icons, and you can simply select the one you want.  There's an option to select more below the preferred types if you don't see the ones you want.
