| 10 | # begins the process of toggling a selection in the listbox. Its |
| 11 | # exact behavior depends on the selection mode currently in effect |
| 12 | # for the listbox; see the Motif documentation for details. |
| 13 | # |
| 14 | # Arguments: |
| 15 | # w - The listbox widget. |
| 16 | # el - The element for the selection operation (typically the |
| 17 | # one under the pointer). Must be in numerical form. |
