Whenever LispWorks is the active application, the LispWorks Toolbar is visible by default.
Initially it appears at top left of your screen as shown in Menus and toolbar in the LispWorks IDE, although you may reposition it as you prefer.
The buttons in the LispWorks Toolbar access the Listener, Editor, Output Browser, Inspector, Class Browser, Generic Function Browser, Symbol Browser, Object Clipboard, Function Call Browser, Code Coverage Browser, System Browser, Compilation Conditions Browser, Grep Browser, Profiler, Tracer, Stepper, Window Browser, Process Browser, Shell and Application Builder tools. Hold the mouse over one of these icons for a second to show the corresponding tool name as floating help text.
You can hide the LispWorks Toolbar. To do this, choose LispWorks > Preferences... > Environment > General and deselect the option Show the tools on a floating toolbar .
