MusicTechHelpGuy breaks down how Logic Pro's edit tools actually work: one tool for a plain left click, another for command click, letting you switch functions without touching the keyboard.
He shows how to add a third slot for right click too, through Logic Pro Settings, General, Editing. That gives you a pointer, marquee, and scissors tool all mapped to your mouse.
He skips the right-click tool himself since it blocks the handy shortcut menu, but flags it as a real option if you want to keep both hands off the keyboard or work mostly one-handed.
A quick reminder on command Z and shift command Z rounds it out, since fast undo and redo matter just as much as the tool setup when you're editing fast.
