Classification of Shortcut Keys

Shortcut keys consist of user-defined and system shortcut keys. After understanding the classification of shortcut keys, you can use shortcut keys quickly and accurately.

Shortcut keys in the system are classified into two types:

User-defined shortcut keys: You can define shortcut keys: Ctrl+G, Ctrl+L, Ctrl+O, and Ctrl+U. You can associate each shortcut key with any command. When you use a shortcut key, the system automatically runs the corresponding command. For details, see Defining Shortcut Keys.
System shortcut keys: They provide fixed functions and cannot be defined by users. Table 1 describes system shortcut keys.

Different terminal software defines shortcut keys differently. Therefore, the shortcut keys on a terminal may be different from those listed in this section.
