Translators: Braille flash messages are similar in nature to notifications or announcements. They are most commonly used for Orca to communicate Orca-specific information to the user via braille, such as confirming the toggling of an Orca setting via command. The reason they are called flash messages by screen readers is that they are shown on the refreshable braille display for only a brief time, after which the original contents of the display are restored. This label is for the spin button through which a user can customize how long (in seconds) these temporary messages should be displayed.
