The modifier command for macros.Follow

Recently, in response to my hotbar simply not having enough keys, I have begun to make macros. Loving them so far (definitely enjoying the nochanelling omnidrain, have a Fear/HoT macro, considering an Immo/Incinerate one as well; and toying with the idea of either Corruption/Seed of Corruption, or one for all/most of my DoTs).

However! Control and Shift, two wonderfully positioned keys, are, unfortunately, already in use. I'm more or less resigned to not being able to use Control (unless I unbound pet commands I don't actually use and moved the rest to the far right end of the bar; will have to see if that works). Shift, however, I would like to get some mileage out of.

Now, with the background information out of the way: Shift + (1-6) brings up various different hotbars. Is there any way to disable that, so that I could use Shift with number-hotkeyed macros instead?

And: If anyone's actually interested, I can post the macros I use. They're really not too fancy, though.

I use Bongos3 for my actionbars and that has the shift+Num bar switching disabled by default.

I love holding shift/control and seeing all my icons change
