====Deciding what hotkeys to add====
Essentially, you want to have a hotkey for each button in your module, as well as a hotkey to focus to each place where the user can provide input or make decisions, such as text input boxes, dropdown lists, or checkboxes. It may be useful for you to map these functions out on a spreadsheet, along with the key you want associated with them and the matching ASCII code.
 
Because the global and local hotkeys have separate modifiers, each module and the global scope have nearly the entire keyboard to work with. The modifiers were chosen because the major browsers have little or no functions already bound to them, however the W T and N keys are off-limits.
 
====Shortcut Help Window====
The Shortcut Help Window, found at dev/bigbluebutton-client/src/org/bigbluebutton/main/views/ShortcutHelpWindow.mxml, is an in-client guide to all hotkeys in the application. The first thing you have to do is add your keycodes into the locale files. For each keycode, you want both the ASCII value of the key and a plain-language description of what the hotkey does. For example, these two lines are the English locale entry for the "focus Presentation window" hotkey already mentioned:
<pre>
bbb.shortcutkey.focus.presentation = 52
bbb.shortcutkey.focus.presentation.function = Move focus to the Presentation window.
</pre>
'''NOTE: It is VERY important that it follow the same pattern of bbb.X, bbb.X.function. Otherwise, the Shortcut Window will not process it correctly.'''
'''REMINDER: After any change to the locale file, you will need to recompile with ant locales.'''
 
Now, we edit the ShortcutWindow.mxml itself. First, in the instance variables you will see a set of ArrayLists (genKeys, presKeys, chatKeys, etc) and a set of corresponding Arrays. You want to create one of each, following the pattern you'll be able to see in the file. For example, let's say that your module lets a user fill in a text box and then click a button to submit their text, and it is called the Opinion module. The instance variables in your ShortcutWindow.mxml should look like this:
<pre>
 
</pre>
