There's Esc. I lost count of how many times I looked at a laptop or a mobile keyboard and got baffled because Esc, a very standard key with no replacement, wasn't there.

Also, the right Alt and Ctrl are quick to go. But somehow there are always buttons for the windows and pop-up keys.

Some laptops manufacturers on my country also think it's a good idea to remove the forward slash and quotation mark. That's because it's the 105° key, and they can't reuse the US 104 keys standard they got from abroad, but well, somehow they think it's not a problem at all.

On the other direction, it's a good thing that desktop keyboards stopped including a "power my computer down" button where most keyboards have delete.

Some people can not understand how standards bring value.

I had really hard time choosing laptop based on availability of those keys!! I really don't know how those thin mac users live... wait, isn't this (once again) one of those Apple's "minimalism" trends? I think so.

On my 2015 MacBook Pro, ⌘+[arrow keys] are respectively mapped to home/end/PgUp/PgDn. That's how I live. In fact I find this interface easier to use than the discrete home/end/PgUp/PgDn keys on my external keyboard, since I have to look at the keyboard to find those as they're not near the home row.

If you’re old time desktop user you wouldn’t have to look for these keys, they’re at the same place for decades. Heck, I even don’t know which combination I’m pressing to go to the begining of page or line, that’s muscle memory at this point.

That said, I acknowledge that you have your own prefered way, and that’s how it should be. As it also should be that these extra keys exist at least on bigger laptops, if not on ultraportables.

I remember using a laptop with Home/End/PgUp/PgDown on Fn + arrow keys. Using those felt very natural. I wish it was more common so I could have the same on my desktop keyboard.

It’s not good to me since I often use these keys with Ctrl or Shift. Adding Fn to the mix would be too much.

Or Ctrl AND Shift, as in Ctrl+Shift+PgDn. I use it all the time. Fn+arrows drive me mad.

Yes, we are a tiny minority. I refuse to compromise on this, and still use a ThinkPad with a 7-row keyboard, but most people have just given up already and went with the mainstream crap. :-(

I use them too, they're really useful for programming and general text editing.
