If you are hurry, you can directly import the HTMLDevelopAccessibility script in your web browser by clicking this link.
When imported into grease monkey or tamper monkey, on simply called by a web page, this script add shortcuts to the web browser that a blind developper with its screen reader can use to explore the html page dom.
With grease monkey or tamper monkey, the blind user could use it on any web site he visits.
Especifically, the script create a virtual field on the current page where a treeview is simulated, and where the user can basically move in the dom with arrow keys.
While moving or using other shortcuts, informations on each important nodes are then given by saying:
the type, name, id and class;
position (left and top)
dimensions (width and height)
colors (background and text) by their code and approximate name
and so on
These are the main keyboard shortcuts added to the web browser:
F2 = say informations on the element under the cursor in the web page. When pressed quickly several times, give instead information for a parent of that focussed element;
Ctrl+F2 = move the focus to the virtual dom explorer
These next keys only work in the dom explorer:
arro keys = move in the treeview of the dom in the virtual dom explorer
b = say the borders of the current selected node in the dom explorer
c = say the colors (background and text) of the current selected node in the dom explorer
d = say the dimensions (width and height) of the current selected node
f = say the font family in the current selected node;
shift+f = open e search dialog to find a node by its tag name
f3 = search the next node with the criteria given in the search dialog;
m = say the margins in the current selected node
n = say the type, name, and class of the current selected node
p = say the absolute positions (left and top) of the current selected node
t = say the inner text in the current selected node
Ctrl+home = go to the first node of the treeview
home = go to the first cibling
end = go to the last cibling
enter = show the current node description in a prompt dialog in order to be selected and copied
