Nisus Writer lets you completely customize any and all keyboard shortcuts. If you don't like the built-in shortcut for a menu command you can change it, or add completely new shortcuts. For example, assign your user-created style a new shortcut.

Multi-key shortcuts are also allowed, which makes remembering all your shortcuts so much easier. For example, you could assign ⌘SC to the Small Caps command.
