Let’s say I want to change the color of a word. I select the word, hit Command-T to open Show Fonts, and then click on the color. Let’s say I click on blue. The word changes to blue.
Now, if I select another word in the outline and click on blue, nothing happens. I have to click on a different color (which works) and then click on blue to change the second word to blue.
If I change word color using the Inspector, I don’t have to add this separate step of selecting another color before going back to the first color.
