# Function Keys

## Standard Function Keys

Serial supports the standard function keys available on a full-size Mac keyboard. The function keys on a MacBook, however, can only be accessed by pressing the “fn” key and then the desired F-key, something that’s almost impossible to do with one hand. As a convenience, Serial provides command-key shortcuts to make these keys more accessible. The shortcuts Command (⌘)-1 through Command (⌘)-0 are equivalent to F1 through F10, respectively.

For Macs equipped with touch bars, the function keys will be displayed in the touch bar.

Serial sends different escape sequences depending on the terminal type selected. If the function keys aren’t working properly, you may need to adjust the terminal type on either end of the connection.

## Soft Keys (VT100 Application Keypad Mode)

When Application Keypad Mode is active (as requested by the device), Serial will treat F1-F5 as SoftKeys 1-5.
