By default, the Line Style toolbar contains quick access tools to change the line attributes of the currently selected markup(s). These tools will be unavailable/dimmed when a markup with no line attributes is selected.
Tools commonly found on this toolbar are described below. The exact tools a user will see depends on their Profile and might not include all the tools mentioned here. For a complete list of tools that can be placed on a toolbar and more information about customizing them, see Tools and Toolbars.
If the toolbar is currently hidden, go to Tools > Toolbars and select it to show it.

Line Start:Sets the graphic style for the start of the line, such as a dot, block, or arrow.
Line End: Sets the graphic style for the end of the line.
Line Style: Sets the style for the line itself, including solid and six dotted variations.
