Online help is available at any time while working in <oXygen/> by going to menu → which opens the Help dialog.
Context sensitive help is available from any dialog or view by pressing the F1 key which opens the same Help dialog directly on a relevant page for the current view or dialog which has the editing focus.
The Help dialog is modal so it does not allow other editing actions in the <oXygen/> editors, views and dialogs. The same help content is available in the view → → (also available from menu → ) which allows editing actions when it is visible on screen and which switches automatically to the relevant help page for the focused editor, view or dialog..
The name and version of the third-party libraries and frameworks used by <oXygen/> are listed in the About dialog box: → Also you can see here the values of system properties like the version of the Java virtual machine, the location of the user home directory, the Java classpath, etc.
