问题:

I use tcsh , and when Delete/End is pressed on cmd line, it simply shows up as ~ ; I have to press <Ctrl><e> to go to end of line. Can anyone help me to be able to use Delete/End keys as their name suggests ?

回答1:

Those keys already worked on my Debian system. I found these commands in the /etc/csh.cshrc file:

if ($?tcsh && $?prompt) then
        bindkey "\e[1~" beginning-of-line # Home
        bindkey "\e[7~" beginning-of-line # Home rxvt
        bindkey "\e[2~" overwrite-mode    # Ins
        bindkey "\e[3~" delete-char       # Delete
        bindkey "\e[4~" end-of-line       # End
        bindkey "\e[8~" end-of-line       # End rxvt
endif

You need to use the bindkey builtin. See the tcsh man page discussion for details (search for 'bindkey'), but you want to add a line like

bindkey [end] end-of-line

to your .cshrc or .tcshrc file, replacing '[end]' with the actual end keypress. See this page for the list of binding names and helpful examples.

There's a great resource on fixing inconsistencies with delete/backspace here. The document also addresses mapping home/end, though that's not the focus.
