You can log on to the SAP systems using SAP GUI for Windows or SAP GUI for Java. The relevant SAP GUI must be installed on your PC.
Whenever the SAP Logon window is open and active, you can use the F1 key to open SAP GUI help. Depending on which window element the cursor is currently on, the information structure opens in the relevant place. From here you can navigate to any other place in the help structure. The help offers a full text search, as you know it from other applications. You start the full text search by pressing key combination CTRL+F.. SAP GUI help is delivered in English and German and is part of your local SAP GUI installation.
Here you can find access to the help function in the menu.
