bindkey problem

bindkey problem

[Manfred Lotz]

Hi there,
If I do
 bindkey '^f' history-incremental-pattern-search-forward

then Ctrl-f does what is expected.

If I do
 bindkey '^s' history-incremental-pattern-search-forward
then Ctrl-s does nothing.

What is my mistake?

C-s and C-q are used for controlling inband flow-control of the terminal
you run zsh in. You can do this to make zsh turn it off:

  setopt no_flow_control

You might also need to do this:

stty stop ''
stty start ''
stty -ixon
stty -ixoff

(from https://coderwall.com/p/ltiqsq)

But maybe that's what no_flow_control is effectively doing.

Yes, probably as no_flow_control was sufficient to turn it off. No additional stty
commands required.

Good question. They're of historic utility (I don't find their default
pause/resume useful), and mostly just cause confusion when
accidentally pressed. Furthermore, it's great to free up a couple more
convenient/comfortable sequences. Traditionally, tools like screen and
tmux use ^a and ^b as their hotkeys. But those have terrible
collisions with emacs/vi bindings. I bind ^q for my tmux "prefix" and
love it. It's also very similar to reaching for vim's ^w window
bindings. Highly recommended tmux binding.

As I never used flow control I wasn't aware of it.

Yep, that does it nicely.
