Interacting with sparky
From NMR Wiki
Most frequently you will interact with sparky via keyboard commands. Each command consists of two keystrokes typed when the mouse is focused on some spectrum - click into the spectrum and type the command.
Alternatively - menu's can be used - either the main window menu or a menu that is accessible trough the mouse rightclick.
Probably the easiest way to learn about commands is to explore the menu. Each menu item contains the shortcut key.
