About orca-3.2.0-xdesktop-cdacmumbai
------------------------------------
orca-3.2.0-xdesktop-cdacmumbai is the enhanced version of orca-3.2.0-xdesktop screen reader.

OSSD, CDAC Mumabi has added following features to orca-3.2.0-xdesktop.
1. List Shortcuts: This helps a new Orca user who finds it difficult to remember the numerous keyboard shortcuts. At the press of a key combination, Orca is ready to speak the list of available shortcuts. The user can navigate the list with Up/ Down arrows. This has become a standard feature for GNOME 2.32 and later. More information can be found at https://bugzilla.gnome.org/show_bug.cgi?id=616820
2. Skim Reading: The skim read feature provides a quick overview of a document. When a user issues "Skim Read' command (Ctrl + KP_Add in desktop, Orca + Ctrl + semicolon in laptop), Orca skims through the entire document. It starts at the current line/ sentence, and then reads only the first line/ sentence of each subsequent paragraph. Whether it reads the lines or sentences depends on the Say All By setting. If the user presses the  Ctrl key, then skim reading stops at the line/ sentence just read. The feature works with Libre/Open Office Word Processor, Gedit text editor and Firefox web browser. More information can be found at https://bugzilla.gnome.org/show_bug.cgi?id=577481
3. Structural navigation in Libre/Open Office Word Processor: This feature enables a user to navigate a Word processor document by heading, table or other document element (image, button, radio button, check box, combo box, list box, entry etc) by pressing a single key. Turn on structural navigation by pressing Orca+z. When structural navigation is on, pressing h takes the user to next heading and pressing Shift+h to the previous heading. Pressing a key corresponding to n (1 <= n <=6) takes the user to the next heading at levl n, and pressing Shift+n takes him to the previous heading at level n.

4. Navigation by sentence:  This feature provides navigation by sentence in Libre/Open Office Word Processor documents and text documents. To read the current sentence, press Windows+/. To read the previous sentence, press Windows+comma. To read the next sentence, press Windows+period. More information can be found  at https:// bugzilla.gnome.org/show_bug.cgi?id=520591
5. Restoration of NumPad functionality: Flat Review takes over NumPad functionality even when NumLock is on. This problem was fixed for the main Orca branch w.e.f. Orca v3.3.4 but not for xdesktop branch.  CDAC Mumbai has fixed the problem for orca-3.2.0-xdesktop. So NumPad keys can be used to type numerals and arithmetic operators when NumLock is On. Additionally, NumLock On/ Off announcements and key echos for Super key and Menu key are enabled. More information can be found at https:// bugzilla.gnome.org/show_bug.cgi?id=690198
