Photoshop lets you view a list of all shortcuts, and edit or create shortcuts. The Keyboard Shortcuts dialog box serves as a shortcut editor, and includes all commands that support shortcuts, some of which aren’t addressed in the default shortcut set.

In addition to using keyboard shortcuts, you can access many commands using context-sensitive menus. Context-sensitive menus display commands that are relevant to the active tool, selection, or palette. To display a context-sensitive menu, right-click (Windows) or Control-click (Mac OS) in the document window or palette.
