The good idea, but...
1) The combinations Ctrl+LeftArrow and Ctrl+Shift+{ are not worked combinations (but Ctrl+PageDown works fine)
2) Is it possible to make combinations without the Ctrl/Command key - simple PageUp/PageDown?

Please add other selectable shortcuts, such as:
Command-Left/RightArrow
Alt-Left/RightArrow
Control-Left/RightArrow

easy to use, just ctrl+page up to go right one tab, and ctrl+page down to got to the left one.. i use it for a game, and it works wonderfully!
