When adjusting text, the text editor and text properties can only select one at a time. It is recommended that you first paste the text into a notepad when copying, then copy it to the text editor. This ensures uniform text formatting, after which you can adjust the font color, font type, and font size in the right-side font properties. The text editor only needs to paste the text in, as adjustments on the right side allow for a more intuitive view of the changes made to the text on the left.
