Welcome back to this series where we’re designing kick-ass keymaps! After covering basics like how good/bad QWERTY is, the power of layers and the potential of custom keymaps, we took the first real steps in designing your tailor-fit keymap by looking into some options for compiling a corpus in general and also with a more useful personal corpus in mind. Quick recap: in this context, corpus is simply a fancy name for a big chunk of text. Today, we’re going to analyze your corpus (or pretty much any text if you haven't done your homework yet) and discuss some basic language statistics along with common metrics that can be used to quickly evaluate a keymap, and also to compare layouts. This is the next logical step in our journey if you're aiming to craft the optimal keymap for yourself. Character/bigram/trigram frequencies To begin with, let's examine the character frequencies in our corpus. The occurrence of different letters can vary significantly not only between...

Figure 1: Zeal's own photo of the first production bags of Zealios switches... I’m guessing that a good number of you reading this article right now clicked on with some sincere degree of confusion from the title. There can’t possibly be any way that ThereminGoat – the guy who has personally tried over 3,000 different switches – is claiming that there won’t ever be another switch like the Zealios, of all things. (I’m sure a few of you are further listing off at least a dozen other medium-heavy tactiles that you can think of that are close enough to Zealios on top of this, too.) While you would be right in calling me out for saying something of the sort about Zealios, the switches, what I’m talking about here is something bigger and more impactful – Project Zealio, a.k.a. the initial groupbuy announcement and ‘Round 1’ release of Zealios switches. I’m here to argue that not only did Project Zealio fundamentally changed the way that the mechanical keyboard community thought...
