For short, simple notes and labels, use single-line text.
A rubber-band line is attached from the text insertion point to the cursor. Click to set the height of the text to the length of the rubber-band line.
You can enter an angle value or use your pointing device.
Text that would otherwise be difficult to read (if it is very small, very large, or is rotated) is displayed at a legible size and is oriented horizontally so that you can easily read and edit it.
If you specify another point during this command, the cursor moves to that point, and you can continue typing. Every time you press ENTER or specify a point, a new text object is created.
