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.
