Toolbar.

The toolbar is way of very quickly accessing common functions directly from a graph window, or for changing the way the mouse pointer (cursor) works.

From top to bottom, the tools are:

Marquee tool- allows a selection to be made in the graph.
Arrow tool- the default tool; has no specific action of its own.
Label tool- opens the Labels Dialog.
Scales tool- opens the Scales dialog which allows the domain, range and type of graph to be changed.
Function tool- opens the Define Function dialog.
Secondary Variable tool- opens the Secondary Variables dialog.
Cut tool- places the current graph or selection on the clipboard.

The toolbar also contains pop-up menus for changing the colours of the graph, scale grid and trace on colour capable Macintosh’s.

A tool is activated simply by clicking it.
