Re: Universal player for Stretch and Buster

This bug of not being able to display subtitles using omxplayer is old (Aug 4, 2019), and I don't know why they don't fix it. VLC media player is not an alternative for all movies since it is slower for x264.

Re: Java Applet

It's more to show old programs. The Java applets still work in IE in Windows 10. It would be good if they also could work in some browser in Raspbian Buster.

Re: Official Raspberry Pi keyboard

You can type the Insert key by typing Fn+Delete on the official Raspberry Pi Keyboard. I miss these keys: Pause, Super R (Right Windows key), Menu, Enter (on the num pad). Shift+F10 is an alternative to Menu, but doesn't send the Menu scan code. I think there should be combinations with Fn that make...

Seems to work.
How do you get those good looking frames in the left screen? I usually get color inverted question marks because my LXTerminal doesn't have CP437, and the emulator doesn't seem to convert to UTF8.

I've read that on some Lenovos without Pause/Break you type Fn+P and Fn+B, but that does not work on the Raspberry Pi Keyboard, e.g. Fn+P types Num Pad -, and Fn+B types b, according to xev .
