You can't mix animation and text, but in the TIM addon, the Catacombs feature will let you enter pages of paragraphs that can then be clicked to insert into text. You have to hit return to send the chat is all. Don't overdo it, ZOS will notice.

For prepared guild info messages, it does the trick.

For RP, you can set up all your prepared dialog, and then just click the button...no more typos.

To do it by hand...use ctrl+c to copy from notepad...use ctrl+v to paste into chat.

Use Wykkyd to make keypress macros for emotes...and you can be very quick at doing combos.

If you use MacroPoetry, you can make a script of animation macros with pauses built in.
You can chat _while_ that macro is running. Voila! You are Richard Burton!

Better yet, using the dangerous "/repeat" command you can make a MacroPoetry script run all the time so that your character is never just standing there like a lump. You can even move around while the macro runs. Etc.
