The most understated “technique” in interface design, ever, and also, the difference between the Microsoft and the Apple school of design:

10. Verbs in labels

You can make options dialogs much more usable by thinking through the labels you use on buttons and links. If an error or message pops up and the options are “Yes,” “No” and “Cancel,” you have to read the whole message to be able to answer. Seems normal, right?

But we can actually speed things up by using verbs in the labels. So, if instead of “Yes,” “No” and “Cancel,” we have “Save,” “Don’t Save” and “Cancel” buttons, you wouldn’t even need to read the message to understand what the options are and which action to perform. All the information is contained in the button labels.

Using verbs in labels on buttons and links makes the options dialogs more usable because the labels contain all of the information the user needs to be able to make a decision.
