Gradient toolbar

The toolbar for the gradient editor contains commands to edit and save the gradient:

The New button creates a new fractal from scratch. To create a new gradient, click New on the File menu and then click Gradient. To duplicate the existing gradient, click Duplicate on the File menu.
The Open and Browse buttons open files from disk.
The Save button saves the gradient to disk. See Opening and saving gradients.
The Undo and Redo buttons can undo and redo changes to the gradient.
The Copy and Paste buttons copy gradients to and from the Clipboard. This is useful for copying gradients between layers or between fractals.
The Fractal button activates the fractal window that owns the gradient editor. This button is not available with stand-alone gradient editors. Together with the Gradient button next to it, you use these buttons to switch back and forth between the fractal window and the gradient editor.
The Select Color, Randomize Color, and Eyedropper buttons change the color of the selected control point. See Editing gradients.
The Insert button adds a new control point. The Delete button removes the selected control point.
The Link Color and Opacity button links and unlinks the color and opacity parts of the gradient. See Transparent gradients.
The Smooth Curves button controls how curves between control points are interpolated: linearly or smoothly.

The commands on the toolbar are duplicated on the File, Edit and Gradient pull-down menus. Frequently used commands are also on the menu that pops up when you right-click inside the gradient editor.
