It's a US keyboard (happens to be a laptop). I've already named the scancodes and VK codes in the parent post. Browser is Firefox.
Backslash works fine if you have chosen to emulate the PC or PC XT. For PCJr, no keystroke appears at all (it does not act as backspace). For Tandy 1000, it acts as backspace. You get the same result whether you use the real backslash key or the backslash key from the on-screen keyboard.
