>From https://askubuntu.com/questions/1153506/how-do-i-enable-all-keys- on-the-touchscreen-keyboard :
The GNOME On Screen Keyboard (OSK) is designed to generate keyboards from the Unicode Common Locale Data Repository data. The Unicode CLDR was never intended to limit the keys available, but that seems to be the path the GNOME developers are following. If a key isn't in the CLDR, there is no way to type it. So, that means, no Esc, no F1, no Control, etc. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1755987 Title: onboard onscreen keyboard lacks arrow keys, pg up/down delete etc To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/onboard/+bug/1755987/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
