Display inacessible informations of page
The intent of this resource is force the screen reader display informations of page that the browser and screen reader may be not display for user nativelly.
The most of browsers has support for keyboard shortcuts, using the acesskey attribute, but the most of browser that has support for keyboard shortcuts not display by default the keyboard shorcuts for user.
The library create a list of keyboard shortcuts of page with the required modifier key of browser and the description of element, the location of this list can be defined by developer or if not defined will be the final of page. The final of page has chosen to not display the list of keyboarch shortcut to user for every resquest, because this can disrupt user navigation. To define the location of the list with keyboard shortcuts of page create a element with the id attribute with container-shortcuts value.
The most of screen readers not display by default the content of title attribute of element, then the library force it to display.
A few weeks ago I spent some time using screenreaders like a blind person would. I used the most popular commercial screenreader JAWS and the most popular free alternative NVDA. It was an incredibly enlightening experience and I learned a lot (here’s a list of what I learned). One of the main things I noticed is that the title attribute isn’t read aloud, AT ALL.

The most of screen readers not warn the user when a link open a new window or tab, then the library force it to display.
The objective of this technique is to provide a warning before automatically opening a new window or tab. Opening new windows automatically when a link is activated can be disorienting for people who have difficulty perceiving visual content, and for some people with cognitive disabilities, if they are not warned in advance. Providing a warning allows the user to decide it they want to leave the current window, and the warning will help them find their way back, if they do decide they would like to go to the new window. It will help them understand that the "back" button will not work and that they have to return to the last window they had open, in order to find their previous location.
