I am a math teacher that uses PowerPoint daily in my class.  I make
the PowerPoints myself, and I am pretty fast at it. I am being slowed
down by the tedious task of putting custom animations. I used Equation
Editor a lot, and I am fast with it. However, when I want to do a Fly
from Bottom animation, I am slowed down by the act of moving my mouse
to the custom animation template, clicking on entrance, then clicking
on Fly in. I want to be able to make the equation or text, and then
just click on a key board shortcut to give it a fly in customation.
Any ideas?

PS- Does anyone know a keyboard shortcut to inserting a textbox.
Again, I find that it slows me down to move my mouse to the input text
icon to insert a text. Any help would be appreciated.
