Nice recommendation. For those who want to see it, watch the video at https://ultimatehackingkeyboard.com/ and at 0:55 you can see the TrackPoint modular add-on.
edit: lol, or just scroll down, it is on the main page.
I'm on a 56 key split right now but I used to use a 48, which had only F2 (of all the F keys) on any layer because it's used for jumping in Sublime Text or Atom or something. Layers vs dedicated keys becomes a matter of preference over chording vs hand movement; some people prefer one to the other.
I don't have a UHK but I have an Ergodox EZ which uses a layer system, similar to the UHK. I have mine setup to where I basically press a Fn key and the number row turns in to F-keys (with a few more to account for F10-F12). It's actually really nice once you get used to it.
