Tools overview
Logic Pro includes a set of tools that you can use for various tasks. When you select a tool, the pointer changes to show the selected tool. Some tools are common to all working areas, while other tools are specific to one or more particular working areas.
A tool (the Scissors, for example) basically affects the regions or events that you click. If multiple regions are selected, they are all affected by the tool (the Scissors tool would cut all selected regions at the same playhead position).
Tools are accessed from the Tool menus, found in the upper-right corner of all windows that allow direct region, event, or file editing and handling operations.
You can assign separate tools to the Left-click and Command-click Tool menus. If you have a suitable mouse, you can also assign the right mouse button. For information about assigning tools, see Assign tools.
