T-Styles is a simple Mac software title that allows the user to store text styles (text color, font, text size…). If you want to use any of them, you can simply select one in the list and then click on the copy button to copy the selected text style into the clipboard. Or you can choose Text Style > Open With TextEdit to let the application directly send it to a new TextEdit document.
