Magtax uses a standard set of controls and icons to help you navigate through the screens. Here are those standard buttons.
Add. This is used to add a new item or entry to the associated list. This is how you add new information.
Edit. This is used to edit or change the selected item in the list. This is how you change existing information.
Delete. This is used to remove or delete the selected item from the list. This is how you remove forms entries, etc.
Help. This is used to display the online help related to the current screen.
Close. This is used to Close the current window. If the window is editing data (if it has an OK / Save button) it will close WITHOUT SAVING any changes.
OK / Save. This button saves the current entry and closes the screen. If this button is displayed on a list, it is used to select the highlighted entry on the list and return that information to the screen that was looking for it.
