The Text Selector Expression is arguably the most elusive Adobe After Effects Feature and yet it's its most powerful Text Feature

This blog aims to provide insights and samples into the mystical world of Text Expression Selectors. Readers are assumed to know how to commit to basic application and adjustments using the Text Tool.
Text Expression Selectors are like mysterious orbs in the sky that everyone sees but only few speak about.
With the Range and Wiggly Selectors, we take note of two critical observations
(1) what gets selected is quite easy to manage and
(2) how each selection is affected by Text Animator Properties is not as easy to manage.
And it is the latter where the Text Expression Selector shines.
Before we proceed, let's define Text Objects Text Object : A group of one or more text characters defined by the Based On Parameter. The Based On Drop Menu provides 4 Group Types Characters, Characters Excluding Spaces, Words and Lines.
You may also create your own Text Objects using any one of these as the basis for grouping.
With Range Selectors, how each Text Object is affected and how it animates involves a complex formula comprising of the parameters in the Range Selector and Advanced Sections of the Text Animator Group.
With the Expression Selector, it's actually a lot easier to manage how Text Objects are affected by the Text Animator Property. The tricky part is that you have to write your own selection and animation functions which are built-into Text Expression selectors that others provide for free or as a paid product.
What you will want to take away from this blog is that Text Expression Selectors allow for more control over how each Text Object is affected by Text Animator Properties.
Let's take a look at a few Text Expression Selector examples because showing by example is always a good way for visual stuff.
What I'd like you to take away from watching this video is to appreciate how text characters are selected and animated with Expression Selectors and how the results here differ from results obtained with using Range and Wiggly Selectors.

To add some brain work into the mix, pause at appropriate samples and ask yourself how you would re-create a sample using the Range and/or Wiggly Selectors.
Chances are you will not be able to replicate most, if any of these Text Animations if you used Range and/or Wiggly Selectors. And with this, the motivation is for you to start venturing into the world of Text Expression Selectors, if you have not done so.

Text Selectors in After Effects Most After Effects users are familiar with its Text Tool and its Range and Wiggly Selectors. However, only a tiny percentage have used the Text Expression Selector.
Advanced After Effects users will have used Expressions in their Range and Wiggly Selectors and even the Source Text Property. Now, let's take a look at the Text Expression Selector.
Text Expression Selector Default Text Expression Selector When you first apply the Text Expression Selector to a Text Animator Group, this is the expression that is applied -
selectorValue * textIndex/textTotal
Unfortunately, for almost every user that sees this for the first time, it's a cryptic line of code. So, let's try to clear this up what you see are essentially three reserved variables; they are functions built into the After Effects Expression Engine.
Before we proceed, let's define these variables/functions
selectorValue * textIndex/textTotal
selectorValue : This is defined as a percentage of the value of the Text Animator Property you apply to the Animator Group.
The selectorValue * ratio is calculated for each Text Object on every frame. I use two different ranges for the selectorValue : 0 and 100 or -100 and 100. They provide different results and you should experiment further appreciate their nuances.
The ideal way to experiment is to link/replace selectorValue with a Slider Control while leaving the other variables in the default expression as is.
There is yet another range that is useful and this accounts for the number of Text Objects available. As this is an introductory article, I will leave this use-case for later.
textIndex : This defines the index of a single Text Object regardless of the type of Text Object selected with the Based On Drop Menu. Each Text Object receives a distinct index.
textTotal : This is the total number of Text Objects based on the Based On Parameter.
Now, let's proceed with some hands-on work
