Tcsh
If you use the tcsh shell, put the following lines in your /etc/cshrc or your
personal ~/.cshrc file: 
#.cshrc
 if ($term == "xterm" || $term == "vt100" \
            || $term == "vt102" || $term !~ "con*") then
          # bind keypad keys for console, vt100, vt102, xterm
          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
 

To see whether it works or not, type: 
[localhost]> source .cshrc
