Doesn't seem to work

[a59]

I installed this per the instructions, but it doesn't seem to do anything.

I type say xyz then the "up arrow", and I get the previous entry from the history.

ETA.

bindkey "$terminfo[kcuu1]" history-substring-search-up does work.
bindkey '^[[A' history-substring-search-up does not

Seeing the same problem on my end - running ZSH on Linux Mint 18.3 Sylvia inside TMUX.

The following key bindings work on my system:

bindkey "$terminfo[kcuu1]" history-substring-search-up
bindkey "$terminfo[kcud1]" history-substring-search-down

Terminfo Reference

My suspicion is that TMUX could be causing some problems, but I'll likely not pursue the problem any further since I got it working on my end with the above bindkey statements.

Good luck!

Hi, I can confirm that "$terminfo[kcuu1]" works under Ubuntu 18.04 whereas '^[[A' etc. fails even though that is what cat -v shows is the key to bind...

That also still works on macOS (where '^[[A' works fine), so it is cross-platform compatible...

[iandol]

Actually, I was wrong about "$terminfo[kcuu1]" working on macOS; it doesn't (tested in Terminal and Kitty). And so if you want a cross-platform solution you need to specify different values for bindkey... 😭

Exactly! We have tried using only terminfo in the past, but soon learned (through user issues) that there is no generic configuration that works for all platforms for binding arrow keys in ZSH. 😩 So instead, we have next best thing: an inexact how-to guide in the README. 😜 I have added your suggestions to the README.
