I feel like I came late to this party, and I'm still kind of a noob here, so... I have a few small-but-nagging questions too.
Apple key modifiers? I see them as an option in the store, but it's not entirely clear if those are substituted on the keyboard when it's assembled, or if they are extra keycaps that I can swap in later. Would like to have both sets on hand. Actually, it seems like quite a few keycap options that have been proposed aren't in the store yet? I'm guessing those will crop up later?
In a similar vein... I understand that you've chosen not to go with Unicomp-made keycaps, but will they still be compatible? I mean, if Unicomp have something I'd like, how well could I expect it to fit and work?
Happy hacking keyboard layouts? I think I understand the split right-shift key, and having a Fn key there seems like a good idea. (Then everything on the bottom row can stay symmetrical as it should be.) Not sure about the top row options.
I see that some layouts have an Esc key in the upper-left, some don't. I know these are programmable, but... If there is no labeled Esc key, what is the usual or default way of handling that? Fn-tilde? Does the HHKB upper row result in Esc on the left, tilde and backslash on the right, and backspace moved down a notch, to just above Enter? Same as a WhiteFox, for example? I could get used to that.
It would be nice to get more information about programming. All I got from the website is that "It's fully programmable!" and "I know nothing about the programming." OK, who does? I'm a programmer myself, so I'm pretty sure I can handle it, however it works.... but I'm curious.
