  * Today we re-visited pointers with the promise that they will become much more powerful and useful to u as we progress.
  * It's significant because, apparently, pointers are very important when it comes to making C programs more efficient and allows more flexibility.
  * When to use pointers may not make perfect sense to me, but surprisingly I understand them fairly well.
  * Recalling the things I learned last semester is difficult, but it's coming back to me.

Fixing delete and backspace behavior in DragonFlyBSD

By default, the delete and backspace keys do not work "normally" in DragonFlyBSD. To fix this behavior for the shell,

add this to /etc/profile

<cli>
export INPUTRC=/etc/inputrc
</cli>

then, in /etc/inputrc place the following

<cli>
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
</cli>

Now when you login again, the behavior should be fixed in the shell.

To fix vim, create a /usr/local/share/vim/vimrc file and add this

<cli>
et backspace=2
set nocompatible
set term=xterm-color
set smartindent
</cli>

Now you should have both your shell and vim backspace and delete keys working a bit more normally.
