"Home" and "End" keys do not work in shell

[ingomueller-net]

Instead, they print [1~ and [4~, respectively. This may be a problem of my setup. I you need to know anything about it, let me know.

I couldn't recreate this issue in Ubuntu 18.04 with bash or zsh shells. It might be caused by your setup @ingomueller-net . I think it would be the best to learn more about what might be causing this. It might enable us to add it to known issues or come up with a fix.

I did just a bit of reading here. Some observations:

• I can use the home and end keys in bash, so I think that the system is configured properly.
• I tried with TERM=xterm and TERM=xterm-xterm-256color with the same result.
• infocmp returns this (in case you know what that means):

$ infocmp $TERM

• This is what showkey shows if I press the home key twice, then the end key twice:

$ sudo showkey --scancodes
kb mode was UNICODE
[ if you are trying this under X, it might not work
since the X server is also reading /dev/console ]

press any key (program terminates 10s after last keypress)...

• The document above says "If the above steps do not resolve the issue, it is probably a program-specific problem rather than a system-wide one." Since I do not have problems with any other application, my guess is that the Sparksoniq shell does not read the system configuration correctly about how to interpret escape codes (whatever that exactly means). Maybe the library you are using for the prompt has information about escape codes/input encoding...?
