You can specify whether you want OK, Apply, Close or Cancel and Help buttons to appear at the top of a command page (for example, in an active tool dialog).
Click then Options. The Options dialog appears.
Click the Mouse tab.
Select the OK/Apply/Cancel/Help buttons at the top of the command page check box. The next time you open a command page, these standard action buttons will appear at the top of the page.
Note: By default, this check box is not selected and these buttons appear at the bottom of the command page.
Click OK to save the changes and close the dialog.
