This project just got upgraded from researching to ongoing, since it should be possible and apparently, 1 additional project helps with moving all projects forward`. #TeTwin Switches [gd0041] is going from a 5-zone, 2 action switch to a 4-zone, 3 action, increasing column states from 11 to 13. Since the keyboard on the Timespy is one handed, it likely means that a single column implementation of this idea is possible. 

Thus, the clickable areas on the screen would be a 13x13 grid. The good news is that I have enough space in this new key layout to include the entire layer without having to switch to some "mouse mode". My main concern is the 76mm long axis, which would be split into 5.85mm zones. This is probably the same sized zone that a finger would have when using a touchscreen, though I think the precision would be half at under 3mm.

A solution is to use the thumb keys. I was wondering about dual-screen use anyway since the OLED screen I'm currently using would be almost the size of 2 standard smartwatch screens side-by-side. The 2 buttons could be for left or right click, and the layers could be left half, right half and a third option, like "don't click", double click or middle click. This solution would have a click area of 2.92 x 3.31 mm, which should be precise enough.
