3. Global options
The "Global Options" on the Braille Sense U2 QWERTY is a large dialog box for controlling many preferences/settings. You can access "Global Options" by pressing "Win key" to get to the main menu, and then navigate to "Global Options" by pressing "down arrow" or "up arrow". Press "Enter" to open the "Global Options" dialog. You can also open "Global Options" from anywhere on the notetaker by pressing "F10". 
You can navigate among the items in "Global Options" using "up arrow" and "down arrow" or using the scroll keys.  You can also use shortcut keys to quickly move to specific items in the "Global Options" dialog. You can toggle an option on or off or cycle through the available values of a setting with the "space" or "Backspace" keys.
To save the changes you've made to the "Global Options" settings, press "Enter". When you press "Enter" to save the settings, the Braille Sense U2 QWERTY says, "Saved options," and you are returned to the place on the notetaker from which you entered the "Global Options". To cancel without saving changes, press the "Esc" key or "Alt-F4". The Braille Sense U2 QWERTY announces, "Canceled saving options". 
From the options list, you can also use "Tab" or "shift-tab" to navigate to the "Confirm" and "Cancel" buttons. If you want to save your settings, press "Enter" on the "Confirm" button. If you do not want to save changes, press "Enter" on the "Cancel" button.
Before we go in to detail about each option, let's first go through a brief overview of what appears in the "Global Options" dialog.

3.1 Global Options Overview
The "Global Options" dialog contains various settings that can be changed in the Braille Sense U2 QWERTY.  As stated above, you can open "Global Options" from anywhere on the unit by pressing "F10". The "Global Options" dialog contains five groups, making it easy to jump to a particular section in the very long list of settings present in the dialog.
1. Braille settings (includes Braille display, Braille cursor, eight dot mode, view/input grade, Braille Code and message display time) 
2. Voice settings (includes language, voice, punctuation level, keyboard echo, capitalization alert, numbers, abbreviations, voice volume, voice rate, voice pitch, Main Volume, Sub Voice Rate, and scroll voice)
3. Display settings (flip LCD display, LCD font size, and video display)
4. Print settings (includes printer port and print paper size)
5. General settings (includes audio alerts, play power on/off sound, left scroll buttons, right scroll buttons, skip empty lines, control information, hide passwords, hot key information, announce shortcut keys, power saving mode, power saving kick in, check today's schedule, one-handed mode, Automatic spell-check, default document type, Automatically synchronize with time server, progress indicator, Bluetooth, wireless LAN, Ethernet port, and mass-storage device mode.)
You can navigate among the five groups by pressing "page down or "page up". When you navigate to a particular group, you are placed at the location in "Global Options" where that group of options begins. Though the "Global Options" dialog is divided into groups for ease of navigation, it is actually one long continuous list of settings. As explained above, you can move between items in the "list" by pressing "up arrow" or "down arrow". You can change the setting for each option by pressing "Space" or "Backspace". 
Note: in addition to navigating by group, you may also use shortcut keys to jump to specific settings in the "Global Options" dialog. However, it should also be noted that often, the same shortcut key is used for multiple options. Thus, as is the case when using first letter navigation, pressing a shortcut key moves the focus to the first setting that matches the shortcut key, pressing the key again moves to the next setting that matches that shortcut key. If there are no more settings matching the shortcut key, the Braille Sense U2 QWERTY wraps around to the first match.
Many items in "Global Options" also have global hot keys. This means you can use this hot key from anywhere on the unit to instantly modify that particular setting without bringing up the "Global Options" dialog.  

3.2 Global Options in Detail
Let's take a look at each setting in the "Global Options" dialog in more detail. 

3.2.1 Braille display
The first item in "Global Options" is "Braille display". When your cursor is placed on this option, you can toggle the Braille display on and off by pressing "Space". The default setting is "On". Use "b" to quickly jump to the Braille display option in the list of items in "Global Options". You can also toggle the Braille display on/off from anywhere on the Braille Sense U2 QWERTY by pressing "F4". 

3.2.2 Braille Cursor
Use this setting to define how you want the Braille cursor to appear on the Braille display. By default the cursor is set to "Always up". Press "Space" to change the cursor to "Blinking," and again to turn the cursor "Off". 
Use "c" to jump quickly to this option. 
Note that the Braille cursor can appear in 3 different forms:
1. "Dots 7-8"
2. Blinking "dots 7-8"
3. Blinking "dots 1-2-3-4-5-6-7-8"
The blinking "dots 7-8" is displayed when you are using "overwrite mode" in the word processor. The blinking "dots 1-2-3-4-5-6-7-8" appears when you are selecting text to denote the end of the selection.
In all other situations, the cursor is displayed as "dots 7-8".

3.2.3 Eight Dot Mode
You can choose to use 6-dot-Braille or 8-dot-Braille mode when entering ASCII text. The shortcut key is "e". By default 8-dot-Braille is set to off. WHEN your cursor is placed on this option, you can turn on 8-dot-Braille mode by pressing "Space". You can toggle this option on/off by pressing "FN-F4" from anywhere.

3.2.4 View/input Braille Grade 
This option lets you choose what grade of Braille you want to use when viewing/entering text.  The shortcut key is "g". The available settings are Uncontracted Braille, Contracted Braille, and Computer Braille. You can cycle among the settings by pressing "Space". You can press "Fn-g" to cycle through the Braille grades from any location on the Braille Sense U2 QWERTY.  

3.2.5 Braille Code
The Braille code setting defines the rules by which Braille is translated to text and vice versa. The Braille Sense U2 QWERTY offers 2 English Braille codes as well as entry of Spanish, French, Italian, and German Braille. Thus the Braille code can be set to use "US", "UEBC", (Unified English Braille Code) or "Spanish", "French", "German", or "Italian". 
The original intent of the UEBC was to explore the possibility of bringing together three of the official Braille codes that are used for Braille in English-speaking countries for various purposes, viz.: literary material (English Braille, American Edition), mathematics and scientific notation (Nemeth Code), and computer notation (Computer Braille Code). 
Choosing one of the other 4 languages allows you to input Braille according to that language's Braille rules, and read documents created in that language using the associated Braille translation. The Braille language also affects, lists, combo boxes, and edit boxes. Buttons and static boxes are not affected by the change in Braille language.
The short cut key used to jump to the Braille code option is "c". The default setting is "US". Use "Space" to change to "UEBC" or "Spanish", "French", "Italian", or "German". 
You can cycle through all the available Braille codes from anywhere on the unit using "Control-Alt-b".
Note: If you change the Braille Code option while you are editing Braille in the Word Processor, the meaning of the Braille in your current document will be changed to reflect the current Braille Code setting. To avoid this problem, the Braille Code option should be changed before launching the Word Processor.

3.2.6 Message Display Time
This option defines how the Braille Sense U2 QWERTY deals with system messages. You can set the unit to ignore system messages, to stand by until you press a key, or, if the Braille display is on, you can define how long the message remains on the display before automatically disappearing. Use "m" to quickly jump to this item in "Global Options". 
The available settings are "Stand by," "Ignore", and display times of 1 to 10 seconds. The default setting is "3 seconds". Use "Space" to increase the message display time by one second and "Backspace" to decrease the message display time by one second.  If you read the message before the display time has elapsed, you can clear the message by pressing any key. 
Set the unit to standby mode by pressing "Space" until you reach "Stand by". In this mode, the message remains indefinitely until you press a key.  If you choose "Ignore," messages are ignored and do not appear on the display. 

3.2.7 Language
The Braille Sense U2 QWERTY can output speech in US English, Mexican Spanish, French, German, and Italian. You can change the Text-to-Speech (TTS) engine using the "Language" setting in the "Global Options" dialog. 
When you change the language of the text to speech engine using this setting, menu items, prompts, and static boxes are not affected and remain spoken in English. However, list items, combo boxes, and all edit boxes and multi-edit boxes, such as documents or e-mail messages, are spoken and text is entered using the language chosen with the "Language" setting. 
When text is entered using a given language, the language attribute is attached to that text, and whenever it is encountered on the unit, it is spoken using the TTS of the language in which it was created. You can change the language associated with a certain block of text using the "Edit Language Attribute" function described in section 5.2.15 of this manual.
The shortcut for jumping quickly to the "Language" setting is "l". Press "Space" to toggle the TTS voice between "English", "Spanish", "French", "German", and "Italian".

If you select "On with characters," each keystroke is announced as you type it. If you select the "On with words" option, each word is spoken after "Space" is pressed. You can cycle through the options by pressing "Space". 

3.2.11 Capitalization alert
Use this option to choose how the Braille Sense U2 QWERTY alerts you that a character is capitalized, either when typing or when navigating a document or edit box by character using "Left arrow" or "Right arrow". The shortcut key is "u". The setting values are "Off", "Say cap," and "Pitch". The default value is "Pitch". If you select the default, when you encounter a capital letter, the pitch of the voice is raised to indicate it. If you select "Off", the voice remains the same regardless of upper or lower case. And if you select the "say cap," option, "cap" is spoken before the letter to indicate capitalization. For example, when you encounter the capital letter "V," Braille Sense U2 QWERTY speaks "cap v".

3.2.45 Mass-storage device mode
Mass Storage Device Mode enables the drives on your Braille Sense U2 QWERTY to be viewed as removable storage devices on a PC when connected via USB. The shortcut key for this option is "d" with the default set to "On". Use "Space" to toggle this option on/off. 
If Mass Storage Device Mode is turned off, the Braille Sense U2 QWERTY can be connected to the PC as a Windows Mobile device and accessed using Microsoft ActiveSync or Windows Mobile Device Center for synchronization of calendar and contacts with Outlook.
When you have finished modifying settings in the "Global Options" dialog, press "Enter" to save the settings. You can also "Tab" or "shift-tab" to the "Confirm" button, and press "Enter". If you do not want to save the settings, "Tab" or "shift-tab" to the "Cancel" button, and press "Enter". You can also cancel saving the settings by pressing "Alt-F4" or "Esc".
