It’s a relatively small difference among the many contrasts between Macs and PCs, but two things Mac keyboards lack that have always been found on PC keyboards are Home and End keys. These two keys can be used to jump to the beginning or end of a page.
With a Mac keyboard, there are two keyboard shortcuts that provide Home and End key functionality.
Fn + left and right arrow keys
Press the Function key and the right arrow key to jump to the end of a page, and Function and left arrow to jump to the top of a page.
Home: Fn and Left arrow.
End: Fn and Right arrow.
Just hold the Fn key down and use the Left and Right arrow keys to replicate the Home and End keys. It’s also worth noting that using Up and Down keys replicate the Page Up and Page Down keys on a PC keyboard.
This keyboard shortcut works on most non-editable and some editable pages. It works, for example, with the new Photos app and iTunes, along with Chrome, Firefox
