How to add hotkeys to sublime text?

Question

Layout

I want to put hotkeys that will save all open files. I found how to do it on the Internet, but if I edit the default file, it does not work at all, if I enter key bindings, I can’t write in the left window. Tell me how to do it please

Answer 1

The left window contains an example configuration. For binds to work, they need to be written on the right.
