yes i did know that actually just forgot that I did. Of course unlike other text manipulation apps, you cannot make a style change to a selection of text, rather to the whole thing. Great and annoying in equal measure I guess. My only, boring but works, work around is to build up the word with different text objects, adjusting the kerning an positioning of each as you would. Put them all in a group so you can move them around and apply filters etc as you would. Of course you cant apply text behaviours to them in the same way.
And the other way is to build the text objects in illustrator or photoshop or whatever, and bring them into motion in some way.
