A short user's documentation
Move inside the user interface
When MozBraille is installed, you can use mozilla normally with the mouse, shortkeys (you can find the shortkeys list here), caret (cursor) and with the "Find as you type" function. For each action MozBraille changes the three outputs.
MozBraille offers you an another way to move inside interface (ie : XUL) and inside HTML document. To do that you have some actions :
- alt-n: Display the next element on the three views and move the cursor.
- alt-shif-n: Display the previous element.
- alt-l: Display the next Braille zone on the Braille output and move the cursor.
- alt-shift-l: Display the previous Braille zone.
- alt-m: Display the next header in the document on the three views and move the cursor
- alt-shift-n: Display the previous header in the document
- alt-p: Display the next paragraph in the document on the three views and move the cursor
- alt-shift-p: Display the previous paragraph in the document
Action on an element
Some XUL or HTML element can do some actions. For example, a link can do the "jump" action. To know the different actions you can open the element configuration window (look this screenshot) . To use those actions you have four shortkeys:
- alt-1: Do the action number 1 on the node under the cursor.
- alt-2: Do the action number 2 on the node under the cursor.
- alt-3: Do the action number 3 on the node under the cursor.
- alt-4: Do the action number 4 on the node under the cursor.

alt-c: Configure the node under the cursor. This action display this windows :
As you can see on this screenshot, you can change what is displayed on the three outputs for each element.
For that you have to use a simple language in three strings.
It's composed with some properties. Each property is represented as "%C" string where C is a character.
Properties depend of the element and are displayed in the config window.
there are three particulars properties:

- %t : is replaced by the element tag name.
