10 | rotate left LVDS1 | |

13 | Only the first letter of each command is checked (case-insensitive), so they | |
14 | can be abbreviated or even cut to one letter each in lower or upper case. | |
15 | ||
16 | For example, the following commands do the same thing: | |
17 | rotate set left | |
18 | rotate SET LeFt | |
19 | rotate s l | |
20 | rotate salad lasagna" | |
