MaNiFeXI not positive about the Vibe but if it is like the Pok3r, the Rt Shift/FN/Meta/Rt CTRL can be set as arrow keys if that helps (but good luck finding keycaps with arrows to fit them :) )
hyperspriteI use an HHKB and other 60%s. I own a VA68M, which is darn close to perfect to me. I would just like to see a 60% with a full nav cluster! Appreciate the info, regardless!
