To close the editor, do one of the following options:
Click the close button ("X")
in the tab of any open editor.
Choose File > Close from the menubar.
Note that you are prompted to save the file before the editor is closed.
Click OK to save your changes and close the editor.
If you closed the editor using File > Close you may have noticed the option File > Close All. This is a quick way to close all of your open editors. If you choose File > Close All, you will be prompted to choose which editors with unsaved changes you want to save.
