| * Provides the Windows look and feel for a text field. This |
| * is basically the following customizations to the default |
| * look-and-feel. |
| * <ul> |
| * <li>The border is beveled (using the standard control color). |
| * <li>The background is white by default. |
| * <li>The highlight color is a dark color, blue by default. |
| * <li>The foreground color is high contrast in the selected |
| * area, white by default. The unselected foreground is black. |
| * <li>The cursor blinks at about 1/2 second intervals. |
| * <li>The entire value is selected when focus is gained. |
| * <li>Shift-left-arrow and shift-right-arrow extend selection |
| * <li>Ctrl-left-arrow and ctrl-right-arrow act like home and |
| * end respectively. |
| * </ul> |
