Ability to save a configuration using CTRL+S shortcut

[FeelProud]

A lot of people are used to saving their current work/task using CTRL+S keyboard shortcut in various software applications. When doing it to in order to save the current configuration changes in the application, it opens the browser's standard 'Save Page' function. It will be a good idea to override the typical browser response to CTRL+S (open the 'Save Page' dialog) by replacing it with saving the configuration changes.
