In Mac Terminal:

• fn + left arrow: scroll to top
• fn + right arrow: scroll to the bottom
• fn + up arrow: page up
• fn + down arrow: page down

I would like to set the action of the fn + left arrow as to be Home of Line as well as End of Line for fn + right arrow. So you can open the Terminal Preference –> Settings –> Keyboard Widget.

 

Double click the key and set the Action to send string to shell: with the following values.

• home key: \033OH
• end key: \033OF

You can now try it out in the Terminal. You can even use these keys in vi. Please note that you have to set it for different Terminal Theme

Done =)
