Nearly all versions of Word have built-in features, which should already
appear in your short-cuts, at the top or bottom, when you open the program.
Yes, you can draw directly on the screen through: freeform, straight lines,
lines ending with arrows, or point. You can also draw through: curves,
scribbles, or dashes. It just depends on what you want. These are AutoShape
drawing features. Should they not appear as a shortcut, in your version of
Word, access your Toolbar settings, and then add a checkmark next to:
AutoShape and Drawing.
