Dear Miketru

Thanks very much for contributing to Keyboard shortcut registry for extension authors (Firefox)

You can be pleased to know that you were first after the originator!

I received a contribution for MouseGestures but had to add that myself!

I have moved your entry for Alt+Up Arrow to just above the same one for LinkToolbar as the sort order of key combination for KeyConfig ignores spaces (ie keys not involved in the combination)). Hence Alt+Up Arrow comes after Alt+Shift+ (anything) even though there is a space in the "Shift+" column. I find it difficult to work it out but the column system is easier to read and maintain.

Please continue to support this small project. I really hope it will be useful.

Best regards, RDL
