OK Buttons

At the bottom of most Daqarta dialogs you will see the standard Windows OK button.

OK accepts all settings and closes that dialog. For those few dialogs which do not have any edit controls, OK is the default button that is activated by hitting the Enter key. The Escape key performs the same function as OK in any dialog, provided you are not in the process of entering a value into an edit control; in that case, Escape will just exit the entry process and restore the original value.

For dialogs with single-line edit controls, you may use the Enter key to conclude an entry. Many users find this more natural than the standard Windows approach of moving the mouse or hitting Tab (which will also work here). In these dialogs, Enter is not the same as OK and will not automatically exit the dialog.

Tab may be used to conclude entry to multi-line controls like Notes and Macro Definition, since Enter alone simply starts a new line.

The Enter key is especially useful if you are trying out different values in a single control. You can type the value, hit Enter, observe the results, and repeat as needed. This saves having to take your hand from the keyboard to move the mouse out of the control and back (or tabbing forward and back) to keep the focus at the same control.
