If you have a long word that needs to break in two pieces on a specific place to go to the next line. Add ­ on the text tab of the editor where the word should break. When you leave the tab, the character is transformed into an invisible hyphen that becomes visible when the word needs to break. If you copy and paste the text with the invisible hyphen in a text editor it also becomes visible.

it breaks in pieces like this

aaaaaaaaa-
