so... a little embarrassed to say, but this will be my first HHKB layout. can i get some tips/advice from those that daily this layout?
What do you use normally?
HHKB layout is my favorite and used it for a good while when my HHKB was my daily driver, but even now most of my boards have some sort of resemblance to the HHKB layout.
If you're coming from TKLs or layouts that have F-keys, you'll obviously have to get used to using the function layer for hitting F-keys. Lack of arrow keys is something to get used to too.
But really the only big things that you'll have to deal with are the repositioning of Control and Backspace. Honestly having Control where Caps Lock was is great for me, since it doesn't require you to exert force with your pinky to hit Control or do some weird twisting of your fingers to hit combinations. Backspace will definitely take some getting used to (provided you actually move it to the \ position), but I love it for reducing travel.
Sorry if this wasn't what you were looking for. But I'm just tryna help.
