A windowed tool that allows you to assign "Hot keys" to font styles where you could quickly edit text on the fly. The text hot key tool would have an activated switch so when its on, it applies your hot keys and when its off everything goes back to normal. This would mostly be used for references where authors names are italicized, body copy is regular and numbers are bold. I know it is similar to the eye dropper tool except you would be able to edit all at once rather than have to go back to each style. The right hand could select the text with the mouse and the other hand uses the hot key buttons to apply the change.
