Ikki68 Camp and Megalodon DOIO Macropad with lubed Banana Milk switches. I’m not a lefty but support moving numpads and nav clusters away from the mouse. Took about 2 weeks to get used to it, and I keep a numpads layer in the Ikki for when I take it away from my main setup.
I use the left for a layer change, middle and right are both space. I wanted to use the middle for another layer, but for many games I need to be able to reach space with my left hand while using mouse to the right.
