Well I actually run Linux now on my MBP but to demystify, I don&#x27;t use any of those keys because I only work in vi. You can do those things without the buttons when not in insert mode:
page up&#x2F;down: ctrl f&#x2F;b
home&#x2F;end: 0&#x2F;$
delete: x<p>Although that&#x27;s somewhat of a simplification for delete.
