Hey Walaber! I encountered a little issue on the web version of Replicube, namely that when I press 0 (zero) on my keyboard (not on the numpad), the developer console opens (also, when I type in the dev console it displays in white on an almost white background; I have the dark mode preference set in my OS / browser if that's relevant). My keyboard layout (Hungarian) is of the ISO persuasion, and it looks like this:

I think on a US / ANSI keyboard the key to the left of 1 is the tilde; on my keyboard, that's "0". And the key that is on the right of 9 on my keyboard is actually the letter "ö", so right now I can only use my numpad to enter "0" with a single keypress on this layout. I was able to reproduce the issue in Chromium 137.0.7151.120 and Firefox 139.0.4 as well on Windows 10.
See scancodes, virtual keys, shift states and more for Hungarian as defined in KBDHU.DLL.
