I'm creating a small web app and I want to be able to toggle it on and off via a keyboard shortcut.
I would like to use one of the function keys (F1–F12). I'm planning on overriding F4, F8 or F9, however I don't want to override one that is commonly used for something else in the browser, in the chance that I share what I'm making with other devs*.
Key | Usage
================
F1 | Help
F2 | ?
F3 | ?
F4 | ?
F5 | Refresh
F6 | ?
F7 | ?
F8 | ?
F9 | ?
F10 | highlights menu in firefox - similar to Alt
F11 | FullScreen
F12 | Dev Tools
Are there any other common behaviors in the function keys that I've missed?
Localized details: The nature of the app makes it inaccessible to visually impaired users. No support for IE is being provided (it doesn't have some required features).
* The target audience is me, and possibly other developers.
