Ah, so in two rows pg up, up arrow, pg down left arrow, down arrow, right arrow I do like that layout, I have an old Dell Precision like that (though even its small keycaps are pretty big). My Framework 13 has the funny full-size left and right on either side of half-height up/down, which is kind of annoying, but you can get used to it, mostly.

Probably my preference over there is half-height inverted T, with just gaps above left and right: I'm happy to do Fn for page up/page down/home/end, and find this is the easiest layout to use by touch. Of course full-height is good too, but only if all four directions are going to be full height.
