When I try to use Command+B/I/U in Pages, I just get the little error sound. I have to type something, delete it, and then use the shortcut, or I have to select it from the menu. This is driving me insane. What is up with this? Also, when you have a bulleted list, double tapping Enter is supposed to end the list. Randomly, this stopped working. Why is Pages so inconsistent? Thanks.
