In general, throughout SIMnet, buttons will correspond with an action and links will be used to navigate to different pages and views. For this reason, it helps to use native screen reader keybindings to cycle through links or buttons, depending on what you want to do. For example, when using NVDA in a SIMbook, the K key can quickly focus the Exit link at the end of the navigation region or the Previous/Next Page links at the bottom of each page.
Most components that shift focus, such as menus and dialogs, can be exited in multiple ways, like exit/dismiss buttons or the Esc key. Certain dialogs are designed to not be dismissible by any student, however, such as those that prevent access to a SIMbook during a closed-book exam. In these situations, exit/dismiss buttons will be missing, shortcuts like Esc will not work, and students must select one of the options provided in order to proceed.
