<C-S>在Vim终端中映射问题

Question

I am having issues trying to map <CS> in Vim terminal.

The same mapping works in MacVim/gVim but not in the terminal. I have tried the below mappings in Terminal.app and the latest version of iterm2 and it fails to work.

Is using <CS> a bad idea because of terminal issues? If it is I was not aware (and could not find any information about it.

nnoremap <script> <buffer><C-s> :call <sid>MyPrivateFunction()<CR>

Note though that the above mapping works in MacVim/gVim but not in the terminal.

I have also tried the following variations:

cmap <script> <buffer><C-s> call <sid>MyPrivateFunction()<CR>
map <script> <buffer><C-s> :call <sid>MyPrivateFunction()<CR>
nnoremap <C-s> :call MyFunction()<CR>

Am I doing something wrong? And again, is it a bad idea to issue such a mapping? What would be the alternative?

Answer 1

<Cs> and <Cq> have been used for decades to do software flow control . You'll probably want to avoid mapping those key sequences in general.
