By Default VSCode only saves the current file when hitting Ctrl+S. Over time, I got used to Ctrl+S saving all the modified files in the project. Here is how to setup the same behavior in VSCode.

This will invert the shortcuts for the
Save All actions. From now on,
Ctrl+S will save all the modified files.
Such a time saver when refreshing your build only to realise you forgot to save one of the files ;)
