Try clicking the tty1-8 buttons, it should pop up a keyboard (but will scroll you to a weird place). I just sent a patch that should fix the scrolling behavior after a tty switch: https://github.com/rsc/unix/pull/1

If you have a different problem, post your OS/browser so we can try debugging it.

Of course I clicked the buttons. It's an inexpensive Android phone on Chrome 118 and Android 11.

Sent a PR with a fix. The problem is that it was relying on the keydown event which Android Chrome doesn't send. Tweaked it to also handle the event input and it seems to work.

OK, thanks. I was able to reproduce it on an Android 11 emulator. I'll take a look. I brought up the tty thing because on iOS it scrolls everything offscreen but input works.
