Additionally, users can navigate between panes and within the contents of the current pane, but cannot magically navigate between items in different panes. Thus, panes represent a level of grouping lower than frame windows or documents, but above individual controls. Typically the user navigates between panes by pressing TAB, f6, or ctrl+tab, depending on the context. | |

| ROLE_SYSTEM_ROW | |
| This object is a row of cells within a table. | |
| ROLE_SYSTEM_ROWHEADER | |
| This object appears to the user to function as a row header, providing a visual label for a table row, and might allow the user to select or adjust values for the entire row. | |
