AE7: How Do I Get Two Different Text Presets On The Same Text Layer At Different Locations?

Object:

Something simple, say, a "crawl in" preset to bring the text in, and
then the text sits there for a second or two, long enough to read it,
and then another, different text preset, an "outro" preset to make the
text leave.

Trouble is, when you do the "right-click" on the text preset, and
choose "Place in After Effects", it apply's the preset to the "entire"
layer that was highlighted.

What I want to do would require a preset in the beginning of the
layer, (intro preset), nothing in the middle, and one at the end,
(outro preset).

Im looking to place presets at exact/specific locations within the
same layer for specified amounts of time. Is this possible, or is this
the incorrect approach to what I wish to do?

Thank You

 

Put the curssor where you want the effect to begin.
It's a no-brainer for the animate on.
For the animate off you still put the cursor where you
want the effect to start, but you don't know where it
will end until you put the preset on the text.
Once it's placed you can look under the "text" dropdown
(on the timeline) and then find an entry called animator.
Typically "animator 1" will be your animate on and
"animator 2" will be your animate off.
There will be a "range selector" under that will be various
options to alter the preset's settings. There will uslually be
keyframes for the "offset" setting. You can alter the speed
and timing of the preset by sliding those keyframes.
