For some special field types, clicking on a field implies that the user wants to interface with the field. A description of each follows:
| Boolean toggle field |
Clicking on the field toggles from the current state to the opposite one. For instance, if a field toggles between the string values "True" and "False" and its value is currently set to "True", clicking on that field toggles its value to "False". |
| Check box field | Clicking on the check box toggles the state of the checkmark. If the field is currently not checked, it is checked. If it is currently checked, it is unchecked. |
| Radio button field | Clicking on a radio button deselects the current radio button selection and selects the clicked field by moving the button to this field. |
| Pushbutton field | Clicking on the pushbutton is the same as pressing the button. The action function associated with that button is immediately called. |
| Multi- toggle field |
Clicking on the field toggles from the current choice to the next one. |
| Spin button field |
Clicking on the spin down button moves the next choice into the field. Clicking on the spin up button moves the previous choice into the field |
| Menu field | If MNCONFIRM is OFF, then the action assigned to the menu field is immediately called. If MNCONFIRM is ON, this menu field becomes the current field, but another click is required to call the action function. |
| CUA border | Clicking on a button in the CUA border performs the appropriate action immediately: minimizing or maximizing the window or displaying the system menu. |
