FnDelete

FnDelete is a keyboard input used on many laptops and compact keyboards to produce the Delete function when there is no dedicated Delete key. It is achieved by pressing the Fn modifier in combination with a key that provides the Delete action in its secondary labeling, commonly the Backspace key, or on some models a key labeled with Delete.

In typical use, FnDelete performs a forward delete: it removes the character or item to the right of the cursor or insertion point. This is useful in text editing, command input, and other interfaces where a forward-delete operation is needed but a dedicated Delete key is absent.

The exact mapping of FnDelete varies by hardware and operating system. On Apple keyboards, Fn+Delete is a standard way to invoke forward delete. On many Windows laptops, Fn+Backspace or an equivalent key combination serves the same purpose, but the specific pairing can differ by model and manufacturer. Some devices also allow changing the behavior of the Fn key in BIOS/UEFI or through vendor software, enabling Fn to act as a standard function key or to revert to the traditional mapping.

To identify how FnDelete works on a given device, consult the user manual or the manufacturer’s support site for keyboard layouts and shortcuts. If it does not respond, check for a Fn-lock or function-key behavior setting in the system firmware or keyboard control software. FnDelete is generally supported on modern laptops but is not guaranteed to be consistent across all models.
