Vim Locking Up, Always When you are Ready to Save? Solution

If you are constantly frustated by Vim freezing up on you are editing a file on a server then this is quite possibly your problem, and your solution.

The issue is that most text editors and IDEs have [ctrl]+[s] mapped to save. If you do a lot of file editing then you probably bash the [ctrl]+[s] combo all the time, without even thinking about it…

Now back to Vim. As it is running in the terminal then it can be frozen by using the [ctrl]+[s] combination. You probably weren’t aware of that feature.

To bring things back to life, just hit the [ctrl]+[q] combo. There are ways to permanently disable this which you can try.
