Many of the pages in ASAP used for data entry, including Registration Forms, Class and Course Edit & External Transcript Entry are designed to work with a keyboard using the tab key to move from field to field to field in the correct order.
If the cursor is not moving to the next field that it should or is skipping a button or not landing on a button that it should be, if you are using the Safari browser on a Mac, you should check your preferences.
On the Safari menu, click Safari | Preferences and click on the Advanced tab. Be sure to click "Press Tab to highlight each item on a webpage". This should resolve the issue.
