Thanks!

Are you sure you typed "BackSpace" and not "Del"?

Maybe this is related to: http://www.macfreek.nl/memory/Backspace_and_Delete_key_reversed

I made the "input" component to accept both the BackSpace and the Delete key. I also fixed a few bugs.

yes, I can confirm that I typed same key in xterm. (ncurses use terminfo for cross-terminal compatiable)

I tried kmscon.

I tried two thing:

terminal_configuration_new.c_cc[VERASE] = "code for backspace"

and

"code for backspace = " = terminal_configuration_old.c_cc[VERASE]

None of them seems to work. I don't know why.

I am using termios in src/ftxui/component/screen_interactive.cpp and the event code for backspace is defined in: src/ftxui/component/screen_interactive.cpp

Closing this old issue. This is a problem for kmscon. I opened: https://github.com/dvdhrm/kmscon/issues/136 but didn't get an answer within 2 years.
