Give visitors an option to set or to turn off the keyboard shortcuts
Some websites allow visitors to use keyboard shortcuts. Keyboard shortcuts make it easier for visitors to perform functions or navigate to a page. This works well for many visitors who use the keyboard but may conflict with some assistive technologies. This can cause shortcuts to be activated unintentionally. This applies, for example, to visitors who use speech recognition software.
Therefore, make sure that single-character keyboard shortcuts can be customized, disabled, or enabled only when the item has keyboard focus.
