The View Menu isn’t particularly useful. You can toggle whether the Tool Box, Color Box, or Status Bar will be displayed here. You can also set the Zoom here, but since you can do that quicker with the Zoom tool, it’s hardly useful. View Bitmap will display the image at full size all by itself with none of the usual Paint window objects to get in the way.

Tip:  If you're looking around in the main Paint window for the Tool Box, Color Box, or Status Bar, and you can't see it, that means they're hidden.  To show them, go into the View Menu and make sure that the check mark appears next to each in the menu.
