Looks like Nyxt, a browser "inspired by Vim", inherits Vim's showstopper bug: Being unusable on many non-US keyboards, at least with the default bindings. The 'switch-buffer-previous' command is bound to C-[, which cannot be pressed e.g. on QWERTZ layouts because the [ character requires AltGr. This is like sending around text files encoded in Windows-1252 and expecting things to just work. Sorry folks, but it turns…
True, Hackers hate changing settings. Imagine if those precious keystrokes wasted on setting a keyboard layout could instead be utilized usefully. Say, to post some cloying, whiny critique of someone else's work, wherein one might go so far as invoking their diety in the hopes it might stem the tide of what, I guess, must be a massive recent influx of vi(m)-keybinding-based projects.
Actually, you probably understand that on a deeper level. Since we are not talking about a product where "you can configure vim bindings in the settings". Its just that you personally appear to like this default and seem offended by others preferring sth else.
