+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.
