No list. See the list of formatting characters when Show Invisibles is enabled in the View menu. You can select any of these characters in your document, and make them the Finder character by Edit menu : Find : Use Selection for Find.
Tabs: \t
Line break: \i (this is the shift+enter character, or soft-return)
Newline/paragraph mark: \n
Non-breaking space: option+spacebar
Suppose I have inserted a Section break after some words, as I have done here:

and on the following section/page, I have decided I want to remove the section break and have the following text appear below the "Some text."
I double-click the section break line to select it, and from Edit menu : Find : Use Selection for Find. Then I open the Find/Replace panel. Nothing will appear in the Find window, despite the section break code being there. I enter a newline \n in the Replace window, and then tap the > arrow to select the section break. It will be lit with yellow, and in the Find window, you will see "1 found." Click Replace, and the section break disappears, and the joined text appears one line below the existing "Some text."
You can also position your pointer in the blank Find window, and then press control+command+Spacebar to open the Character palette. In the panel's search window, you can enter the type of character you seek, and then double-click that character to insert it into the Find window. You would use this if there were a special character in your document that you wanted to change or remove (nothing in the replace window).
