Maybe the problem is rooted in different shell versions emitting different key
codes:
Here are the used versions of shells and terminals
| zsh | bash | xterm | rxvt-unicode | st |
+-------+--------+-------+--------------+------------+
openbsd | 5.0.2 | 4.2.45 | 301 | 9.19 | latest git |
debian | 5.0.5 | 4.3 | 301 | 9.19 | latest git |
Results:
CTRL-v + HOME on openbsd:
| zsh | bash | ksh |
+-------+-------+-------+
st | ^[[H | ^[[H | ^[[H |
xterm | ^[OH | ^[[H | ^[[H |
rxvt | ^[[7~ | ^[[7~ | ^[[7~ |
CTRL-v + HOME on debian testing:
| zsh | bash |
+-------+-------+
st | ^[[1~ | ^[[H | <- newer zsh on debian emits ^[[1~
xterm | ^[OH | ^[[H |
rxvt | ^[[7~ | ^[[7~ |
CTRL-v + DEL on openbsd:
| zsh | bash | ksh |
+-------+-------+-------+
st | ^[[P | ^[[P | ^[[P |
xterm | ^? | ^? | ^? |
rxvt | ^[[3~ | ^[[3~ | ^[[3~ |
CTRL-v + DEL on debian testing:
| zsh | bash |
+-------+-------+
st | ^[[3~ | ^[[P | <- newer zsh on debian emits ^[[3~
xterm | ^[[3~ | ^[[3~ | <- newer zsh on debian emits ^[[3~
rxvt | ^[[3 | ^[[3~ |
Any comments?
