There are many keyboard shortcuts in Oracle to help you navigate through the various fields / screens faster.
Standard keyboard shortcuts such as Save (CTRL+S), can be used whenever you want to save a new or, updated entry and Exit (ALT+X) to go back to the previous screen.
The keyboard shortcut CTRL + K anywhere in Oracle can be used which will give you the keyboard shortcuts for the specific screen.
An example is to use the CTRL+K to get the list of keyboard shortcuts for the SEAMAN DETAILS main screen.
