Great feedback DreymaR, exactly the kind of detail I hoped I would get, thanks man!
Not sure how you did those, Ctrl+Right/Left mapped to the L/Y keys?
I'm a MacOS user, option + left or right will move the cursor to the start of the previous word or the end of the next word. Using QMK, I have bound these to Extend - L and Y (I'm pretty sure there is a Windows equivalent - ctrl perhaps? Am I right?).
By holding Extend - shift - L or Y, I can select the previous/next word respectively - so selection is perfectly achievable.
Multimedia keys aren't used that often, so they don't quite deserve to be smack dab in the middle of things? Well, with multiple layers it's okay I guess.
That's right - I use the multimedia keys often enough that I want them on the default layer - this is a feature I miss from years of using an Apple 65% board. The default keycaps for those positions are from the navigation cluster:
so perhaps it is better to keep those as THE default for most users (and move multimedia keys to the extend and/or function layer). I can't help but think that the added navigation options around the right hand on the Extend layer means they aren't need as dedicated buttons any more? I guess this part is down to preference.
Key mousing doesn't work well enough for a central placement in my opinion
I totally agree - Unless there is a trackpoint or similarly responsive input device, I think the qmk implementation of mouse movement is shaky at best.
Whether to use a number row like yours or a NumPad like mine is a matter of preference I guess. The NumPad could be very fast and comfy, but takes some training.
Actually, I have considered adding a num lock toggle button for this purpose! The ideal position imo would be the back-slash key (between the 5 and 6 on the number row) - of course a back light to indicate that it's on would be ideal, but maybe that's something for the second revision of the PCB?
I do, however, strongly recommend your alternative setup as separating the /? key from the others is a bad thing!
Personally, I agree. This arrangement reflects a common trend in the popular keyboard layouts over at reddit.com/r/mechanicalkeyboards, so I wanted to include it as an option. I'd like to try it out before I give up on it though ;)
