+Why doesn't the Del key work in some programs?
+
+Taken from the terminfo manpage:
+
+       If the terminal has a keypad that transmits codes when the keys
+       are pressed, this information can be given. Note that it is not
+       possible to handle terminals where the keypad only works in
+       local (this applies, for example, to the unshifted HP 2621 keys).
+       If the keypad can be set to transmit or not transmit, tive these
+       codes as smkx and rmkx. Otherwise the keypad is assumed to
+       always transmit.
+
+In the st case smkx=\E[?1h\E= and rmkx=\E[?1l\E>, so it is mandatory that
+applications which want to test against keypad keys, have to send these
+sequences.
+
+But buggy applications like bash and irssi for example don't do this. A fast
+solution for them is to use the following command:
+
+       $ printf "\033?1h\033=" >/dev/tty
+
+or
+       $ echo $(tput smkx) >/dev/tty
+
+In the case of bash readline is used. Readline has a different note in its
+manpage about this issue:
+
+       enable-keypad (Off)
+               When set to On, readline will try to enable the
+               application keypad when it is called. Some systems
+               need this to enable arrow keys.
+
+Adding this option to your .inputrc will fix the keypad problem for all
+applications using readline.
+
+If you are using zsh, then read the zsh FAQ
+(http://zsh.sourceforge.net/FAQ/zshfaq03.html#l25):
+
+       It should be noted that the O / [ confusion can occur with other keys
+       such as Home and End. Some systems let you query the key sequences
+       sent by these keys from the system's terminal database, terminfo.
+       Unfortunately, the key sequences given there typically apply to the
+       mode that is not the one zsh uses by default (it's the "application"
+       mode rather than the "raw" mode). Explaining the use of terminfo is
+       outside of the scope of this FAQ, but if you wish to use the key
+       sequences given there you can tell the line editor to turn on
+       "application" mode when it starts and turn it off when it stops:
+
+               function zle-line-init () { echoti smkx }
+               function zle-line-finish () { echoti rmkx }
+               zle -N zle-line-init
+               zle -N zle-line-finish
+
+Putting these lines into your .zshrc will fix the problems.
