I was aware of the Emac-isms (as I think of them) of C-a and C-e for start and end of line in the terminal and elsewhere in Mac applications. But do those two serve the same function that Home does in applications where Home and End send you to the start or end of the whole page? To put it in terms I'm more comfortable with, I thought that in some contexts Home was like Vim's gg. For example, I just opened Safari. fn + right arrow brings me to the bottom of the page; fn + left arrow brings me back to the top of the page (home and end). In that case, C-a and C-e do nothing. I'm not really sure if you're wrong or I'm very confused or both at this point. But I don't think C-a and C-e are exactly Home and End. (I suppose it doesn't help that in a browser, there's another Home - ^⌘H in that case.)
