Which one is the delete button on an Apple keyboard?

Solution 1:

In a text editor…

Fn Backspace ← is the equivalent of Delete ⌦ for short keyboards without that key

  • Backspace ← deletes the character before the cursor.
  • Delete ⌦ deletes the character after the cursor.

  • Cmd ⌘ Backspace ← deletes the entire line before the cursor.

  • Opt ⌥ Backspace ← deletes the word before the cursor.
  • Opt ⌥ Delete ⌦ deletes the word after the cursor.

In the Finder…

  • Cmd ⌘ Backspace ← deletes the selected file(s).
  • Cmd ⌘ Delete ⌦ has no function.

To summarize:

  • The most commonly used key for deleting elements that can be selected in the user interface is Backward Delete since it's available without a modifier on all Apple keyboards. This applies to songs on a playlist, graphics in an image editor, deleting text boxes in Pages, etc.

  • The Forward Delete fn is mostly used for the same actions, so you can actually use both in an interchangable way for most applications, be it Numbers, Excel, iTunes, Photoshop, etc.

  • The combination is intended for actions that might have an immediate (unwanted) effect. One could indeed map trashing files and folders to a simple , but this could lead to accidental deletions. Finder uses the modifier as a safeguard. This also explains why iTunes will only delete a song without confirmation if you press the modifier.
