With the offline programs the convention (at least in English) is to type Ctrl+S to save a document. However, in many online web(app)s the convention is to type Ctrl+Enter to submit the current form, normally used for comments. However, Shift+Enter might be used to NOT submit a form.
The thing is quite complicated, and it highly depends on each page to provide a shortcut for submitting the current form. This is okay in empty
<textarea>s since they can provide a placeholder to explain this, but not so much when editing. So the question is:
Is the Ctrl+S shortcut still relevant for websites when editing a document such as a blog post or other long texts? (overwriting the 'save this page' functionality)
