+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:
+
+ $ echo ^[?1h^[= >/dev/tty
+
+or
+ $ echo $(tput smkx) >/dev/tty
+
+In the case of bash it is using readline, which has a different not in its
+manpage:
+
+ 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.
