Save as new
Create a new brush. This leaves the original brush unchanged.
Save
Update the selected brush with these changes. If you have edited one of the default brushes, clicking Save creates a new brush in the document.
Close
Any changes apply only to the selected line (if any). This leaves the original brush unchanged.
Notes:
Xara LX saves only brushes
used in the document. It discards unused brushes when you quit the program.
To ensure a brush always gets saved, draw a line in the gray pasteboard
area and apply the brush to that line. (Items in the pasteboard area are
non-printing.)
To edit or add to the default
set of brushes, see this page.
