Have a problem with vim settings?

Question

nmap <c-s> :w<CR>

In the vimrc file, I added the code shown above, but pressing ctrl+s had no effect when I used vim later. May I ask why?

Answer 1

The problem has been solved, you need to add the following two lines to the ~/.bashrc file

bind -r '\C-s'
stty -ixon

Answer 2

? ? ? ctrl+s? ?
What do you want to do, save?
Save in vim is: w, exit is: q
The effect is better when combined with the two

Answer 3

x is to save and exit

Answer 4

Save and exit isn’t it ZZ?
