For some reason, the Home and End keys don’t work as you might expect in Mac OS X’s Terminal.app. Instead of moving the cursor to the start and end of the current line, they scroll to the top and bottom of the window’s scrollback history.

You can get the behviour you might expect by pressing Shift+Home and Shift+End, but this is awkward. To fix this and make Home and End do what you expect:

1. Open a fresh terminal window
2. Choose Terminal->Window Settings from the menu
3. Select “Keyboard” from the drop down list
4. Select “End” in the list and press Edit
5. Choose “send string to shell” and then move to the textbox
6. Press <Esc> (33 will appear) then type [F. Press OK.
7. Select “Home” in the list and press Edit
8. Choose “send string to shell” and then move to the textbox
9. Press <Esc> (33 will appear) then type [H. Press OK.
10. Press “Use Settings As Default”
