By clicking on the down-arrow, you can specify any of the following conversions:

Lower Case	this is an example.
Upper Case	THIS IS AN EXAMPLE.
Mixed Case	This Is An Example.
Sentence Case	This is an example.
Invert Case	tHIS IS AN EXAMPLE.

This is a special "Drop-Down" button, usually displayed with a drop-down arrow. If the arrow is present, then it will bring up a menu of the four conversions. If you don't have the drop-down arrow present, then clicking on the button will always bring up the menu.
