Correct keyboard shortcut for a Web Application
===

All,

I am documenting the keyboard shortcuts for our web application. Please share if these are not the right keys to use, for any reason, such as interference with browser's own keyboard shortcuts/ OS shortcuts or general usability's sake.

The shortcut initiator will be 'spacebar', similar to how some gmail shortcuts use '*' as initiator. The list of shortcuts is rather big but here are a few of the key ones:

**functionality - shortcut**

SAVE - spacebar S

Undo - spacebar Z

Redo - spacebar Y

Our Web Application is a one page, without scroll, Js application. We are cosidering John Resig's [Hotkeys][1], [Mousetrap][2], [jKey][3] for the plugin. Any thoughts, warnings would be much appreciated on the use of the above keyboard shortcuts.
