Content is displayed on a touchscreen display of a computing system such as an electronic book reader. The content is displayed according to a setting for a first attribute (e.g., level of brightness) and a setting for a second attribute (e.g., day mode or night mode). In response to sensing a motion proximate to the touchscreen, the setting for the first attribute is changed to a different value. In response to a value for the setting for the first attribute crossing a threshold value (e.g., while the motion is being performed), the setting for the second attribute is changed.
