Once you have selected which projection to use, click on the Convert to Specified Map Projection button to process the conversion on the shapes currently in memory.

You also have the option to shift the XY coordinates of shapes or scale them by scalar values. To shift shapes, enter scalar shift values for the X value and Y value and press the Shift XY Data button. To scale the XY coordinates, enter scalar scaling factors for the X and Y value, and press the Scale XY Data button.
