Indexing and tagging

Though we managed to leverage some built-in functionalities to gain a quick advantage, we need more control over the text area so that we can bend it to our will. This will require the ability to target each character or text location with precision.

We will need to know the exact position of each character, the cursor, or the selected area in order to do anything with the contents of the editor.

The Text widget offers us the ability to manipulate its content using index, tags, and mark, which let us target a position or place within the text area for manipulation.
