DECELF—Enable Local Functions
This control function lets you enable or disable the keys used to perform several local terminal functions: cutting and pasting text, panning, and resizing windows. DECELF is useful for:
- Simplifying the keyboard for novice users
- Letting the corresponding keys send position codes to the host when key position mode (DECKPM) is set
- Disabling features that are not compatible with the application
