Metacharacter
Connotation
{n,m}
The matches appear for n-m times (m and n are non-negative
integer and n is smaller than or equal to m).
Note that there is no space between n and m.
For example:
^ip: matches the target object that begins with the character string "ip".
ip$: matches the target object that ends with the character string "ip".
The simplest regular expressions do not contain any metacharacter. For example, when a
regular expression is defined as "hello", it matches only the character string "hello".

The shortcut keys in the system are classified into the following types:
z
User-oriented and user-defined shortcut keys: CTRL_G, CTRL_L, and CTRL_O. The
user can correlate these shortcut keys with any commands. When the shortcut keys are
pressed, the system automatically runs the corresponding command. For the details of
defining the shortcut keys, see
Defining Shortcut Keys
.
z
System-defined shortcut keys: These shortcut keys with fixed functions are defined by
the system.
Table 3-7
