You can use a Heads-Up Display toolbar that appears when you select entities in the graphics area.
Using Heads-Up Display, you can quickly zoom to the specified entities, change the entities Layer, LineStyle, and LineWidth, dimension entities, or create a Block from the entities.
You can turn the Heads-Up Display on and off.
The toolbar is draggable. If you do not click an option, it disappears shortly thereafter. To redisplay it, specify an entity that you already selected.
