The keyboard in the photo was bought from Amazon in the UK, as "Black Left-Handed Mechanical Keyboard".

I am indeed a right-handed user, which is why I want my mouse within reach on the right.

I believe it's this keyboard[1] from Posturite, but doing a web search for "Left-Side Numpad" of "Left handed keyboard" should show a few options.

I went to https://www.keyboardco.com/ and searched for left-handed and the keyboard in the photo popped up, as well as a bunch of weirder and wonderfuler ones.

Personally I just switched to TKL keyboards (no numpad). While I did use it occasionally, it wasn't often enough to feel inconvenienced without it... All the buttons are still there after all, and if I'm already at home row, it isn't any slower.

May be worth considering too, especially if you're looking for a good keyboard with eg magnetic switches vs shitty rubberdome

Yeah I would suggest you stick some wood on your left side of your current keyboard, for a few days to see if you can adapt... I always used that space as a resting place, so having it occupied totally broke my flow.

(If I needed a numpad I would have it standing alone.. those are easy to find)

keychron does make one: https://www.keychron.com/products/keychron-q12-max-qmk-via-w...

found this one as well, don't know the brand: https://www.bloodyusa.com/product.php?pid=11&id=166

yeah that keyboard is definitely different than what I'm accustomed to. My son pointed out that shift-2 is not '@' but '"'.
