2.4 Shortcut Keys

Using the system or user-defined shortcut keys makes it easier to enter commands.

2.4.1 Classifying Shortcut Keys

There are two types of shortcut keys, namely, system shortcut keys and user-defined shortcut
keys. Familiarize yourself with shortcut keys so as to use them accurately.
The shortcut keys in the system are classified into the following types:

Key or Command
display history-
command
Up cursor key (↑) or
Ctrl_P
Down cursor key
(↓) or Ctrl_N
NOTE
On the HyperTerminal of Windows 9X, cursor key ↑ is invalid as the HyperTerminals of Windows 9X
define the keys differently. In this case, you can replace the cursor key ↑ with Ctrl_P.
The saved previously-used commands are the same as that those entered by users. For
example, if the user enters an incomplete command, the saved command also is incomplete.
If the user runs the same command several times, the earliest command is saved. If the
command is entered in different forms, they are considered as different commands.
For example, if the display ip routing-table command is run several times, only one
previously-used command is saved. If the display current-configuration command and
the display ip routing-table command are run, two previously-used commands are saved.
User-defined shortcut keys: CTRL_G, CTRL_L, CTRL_O, and CTRL_U. The user can
correlate these shortcut keys with any commands. When the shortcut keys are pressed, the
system automatically runs the corresponding command. For details of defining the shortcut
keys, see 2.4.2 Defining Shortcut
System-defined shortcut keys: These shortcut keys with fixed functions are defined by the
system. Table 2-7 lists the system-defined shortcut keys.
