By default when you use FreeBSD’s BASH shell and if you hit Home, Del, Insert keys all of them just prints ~ (some garbage is printed ). To get rid of this problem, edit /etc/profile file and define key binding.
1) Open your bash global profile file:
# vi /etc/profile
2) Add following line to it:
export INPUTRC=/usr/local/etc/inputrc
3) Close and save the file
4) Open the file /usr/local/etc/inputrc and define / modify key binding:
# vi /usr/local/etc/inputrc
5) Append following config data:
set meta-flag on set input-meta on set convert-meta off set output-meta on "\e[1~": beginning-of-line "\e[4~": end-of-line "\e[5~": beginning-of-history "\e[6~": end-of-history "\e[3~": delete-char "\e[2~": quoted-insert "\e[5C": forward-word "\e[5D": backward-word
6) Close and save the file
7) Now logout and login back again to test your new key settings.
