I'm thinking about creating some keyboard shortcuts to my web application. But, most of the important shortcuts are already attached to the browser itself (like F1, F2, Fn; Ctrl+N; Ctrl+P, Alt+P, Alt+A, etc...)
I've notice that the browsers don't use any Shift+Key combination. But, Shift+Key are already reserved to type uppercase letters, so, I think using Shitf+Key combinations isn't a good idea.
Is there some guidelines to write keyboard shortcuts in the web?
Or, should I give up using it?
