To create a
command tool from the Customize User Interface
Right-click on the title bar of a tool palette. Click Customize
Commands to open the Customize User Interface (CUI) dialog box.
If the Tool
Palettes window is covered up, move the CUI dialog box off to the
side.
In the Command List pane, drag a command to the tool palette
and, without releasing the mouse button, move the cursor to the
place on the tool palette where you want the tool.
The black
horizontal line indicates where the tool will be located.
