Choosing Buttons on Toolbars 

Toolbar buttons in R/3 transactions are associated with keys, which are included in the SAP Automation GUI keys collection.

With the R/3 3.0 GUI, these keys are usually listed in the quick info (that is, the ToolTip) for each toolbar button. Comparing the ToolTip or the toolbar button name with the list of keys available for an event will usually lead to the key to use to access a certain button.

See the topic Windows Virtual Key Values for listing of the key values.
