I've found ^S mapped to be the fwd-search key for zsh (ohmyzsh) but I would like to use it in vim for various mappings as well - it seems like the zsh mapping is preventing me from using it now.

Any way to unmap the bindkey or have it both ways?

Are you sure that it's oh-my-zsh? I couldn't find anything in its sources where bindkey maps Ctrl-S. – Daniel Beck Feb 2 at 15:15
yeah, i think it is actually default zsh - i mention ohmyzsh in case there is something there that might be important as well - i'm still new new zsh – liamgriffiths Feb 2 at 15:23
On my system (never used zsh before) Ctrl-S suspends, as it should. Have you checked your zsh profile files? – Daniel Beck Feb 2 at 15:26
i'm still digging around - hoping i could find insight here faster :-) ... previously bash for me worked out fine with C-s – liamgriffiths Feb 2 at 15:27

This is probably flow-control, which is handled by your terminal and not your shell. Typically control-s stops terminal output, and control-q resumes it. See the note in ":help ctrl-s".

To remove this behavior, you could try these shell commands:

stty stop undef
stty start undef

This may not work, though. If you are using a GUI terminal emulator, try looking for flow control settings within its options.
