What is a text-object?

Instead of editing character by is much more efficient to edit by word, sentence, and paragraph. In Vim, these higher-level concepts are called text objects. But in the end just a block of text. If you want to go deeper take a look at this post and also the official documentation :h text-object.

How to memorize all the shortcuts that can come out of this plugin?

My approach is to do some sort of artificial selection. Add the commands you like with the most straightforward shortcut, being concise and having meaning for you. After having it for some time you go back and clean it up if you did not use it.
