A family of Microsoft word processing software products for creating web, email, and print documents.
In Word, you can use ^p in the Find & Replace dialog box when you search for a paragraph mark (represented by a pilcrow, ¶, if you display nonprinting marks in your documents). See the screen shot below which is from Word for Windows. (Word for Mac will be similar, but not necessarily identical.)
To insert special characters using Word for Windows, use Insert tab > Symbols group > Symbol > More Symbols.
The dialog box has a Special Characters tab which lists characters and their shortcuts. You can assign your own shortcuts if you wish.
