2.2 Special Functions

Special functions use the Control (Ctrl) key, displayed in the help and shortcut lists as ^; the Meta key, displayed as M; or the Escape (Esc) key.

• Control key sequences are entered by holding down the Ctrl key and pressing the desired key, or by pressing the Esc key twice and pressing the desired key.
• Pressing Esc twice and then typing a three-digit number from 000 to 255 will enter the character with the corresponding value.
• Meta key sequences are entered by holding down the Meta key (normally the Alt key) and pressing the desired key, or by pressing the Esc key once and pressing the desired key. Certain operating systems "swallow" the Alt key so that it never reaches the application; if your operating system does this, you should use the Esc key to generate Meta key sequences.
