Edit text without Home, End or Forward Delete

A Mac laptop keyboard has no Home, End or Forward Delete key, and the key labelled Delete deletes backwards. The missing keys are all there as shortcuts:

• Fn + Delete deletes forwards, the character to the right of the insertion point.
• ⌥ + Delete deletes the whole word to the left.
• ⌘ + ← and ⌘ + → jump to the beginning and end of the line.
• ⌥ + ← and ⌥ + → jump a word at a time.
• ⌘ + ↑ and ⌘ + ↓ go to the start and end of the document.

Add ⇧ to the movement shortcuts and they select as they move: ⇧ + ⌘ + ← selects back to the start of the line.

The pattern to remember is that ⌥ works on words and ⌘ on lines and documents.
