VT Keystrokes

The sendKeys method (of the ScreenVt object) sends characters and function keys to a VT 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 VT function key.

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

Note The @ style mnemonics are case-sensitive.
