ALC Keystrokes

The sendKeys method (of the ScreenAlc class) sends characters and function keys to an ALC terminal session. Function keys, such as the Transmit key, are represented with codes called mnemonics. Use the table below to identify the mnemonic that represents a particular ALC function key.

You can send keys using either the brace style or the @ sign style.

Note The @ style mnemonics are case-specific; for example, @Z represents Cursor right, whereas @z represents the dollar sign ($).
