There doesn't seem to be an fn key on this keyboard, how do I adjust backlight brightness?

Welcome back to our series on designing custom keymaps! After looking into how good/bad QWERTY is, the power of layers, and the potential of custom keymaps, last time we took the first real step by examining your options for compiling a corpus. As a recap: The corpus is simply a big chunk of text. We use this collection of textual data, often a single text file, to characterize your typing habits (calculating various language statistics), and feed it directly or indirectly as an input into layout optimization algorithms – to find the optimal keymap for you! Today we’ll expand on this idea by exploring your options if, like me, you prefer a personalized corpus rather than grabbing some general (and mostly irrelevant) data available online. Image 1: Letter frequencies – the most basic use of corpora – in this very post We've seen that a well-crafted, personalized corpus plays a key role in determining the outcome of the optimization process. We've also explored...

Hello! I really love this (large) font and understated design of these keycaps, but the problem is that despite this picture I got off Reddit, I can't find them in a shine through version anywhere. Can anyone tell me where I can find what I'm looking for? I will be putting them on my Royal Kludge S98 (Lavender), if anyone is curious, and I hope I can find a color variation that would look nice on the S98. Thanks in advance!
