Set up a stroke to access the Stroke Preferences dialog > Use the stroke
With the Stroke Preferences dialog you can save sets of strokes and set other stroke properties.
Note: By default, the Strokes Preferences dialog is available only if you assign a stroke to it, then use the stroke to access the dialog. See the following procedure.
To access the Strokes Preferences dialog:
Set up strokes for your left or middle mouse button. See Strokes for information how to do this.
To define the stroke, hold down CTRL and drag an inverted L shape (drag vertically from bottom to top, and continue from left to right).
On the Define Strokes dialog, choose Stroke Preferences from the list.
Drag an inverted L shape to access the Strokes Preferences dialog.
