Many of the program's windows in which you enter information have three
main buttons:
Save - the
button saves the changes and closes the window. If you want to save
the changes without closing the window, select the Apply option
from the drop-down menu.
Cancel - the
button discards the changes. If you don't want to close the window,
select the Discard
option from the drop-down menu.
Refresh data - the button
refreshes the data. This button is available in most windows which
work with data.
