13.7.2 Terminal Clipboard

Terminal Clipboard allows you to create and edit text on the notetaker before sending it via the Terminal for Screen Reader to the connected device. This can be useful in instances like when using VoiceOver on an i-device, in which characters are translated as they are sent to the IPhone or iPad. In this case, if you do not type quickly, characters may be mistranslated. For example: if you type "t e l l" and do not type quickly enough, VoiceOver could potentially translate this as "thateverylikelike" as, if there are pauses in typing, each Braille character can potentially be translated to its whole word equivalent. In the same way, editing text is also difficult as, any letter or single character Braille contraction, when typed by itself is translated as that contraction. So, if you are attempting to type the word "talk", and accidentally type "tall", when you delete the "l" and type the "k" the "k" is translated as "knowledge". Thus, the text you get is "talknowledge". To truly fix the word, you must erase the entire word and type it again.
Thus, creating/editing text when using your notetaker as a Braille display is sometimes a very exact and tedious business. As explained above, the Terminal Clipboard allows you to create and edit text on the notetaker, and send the completed text to the connected computer or SmartPhone via the Terminal for Screen reader.
To enter "Terminal Clipboard", press "Space-Enter-I (dots-2-4)". The Braille Sense announces, "Terminal Clipboard". Type and edit your text using normal text entry and edit commands. In "Terminal Clipboard", the Braille display and keyboard are temporarily disabled from sending/receiving information to/from your connected computer or i-device, so that you may use them for creating/editing your text. For more information on text entry and editing, please see section 5 of this manual on the Word Processor. When you are finished typing the text you wish to send to your computer or PDA, press "Enter-S (dots-2-3-4)" and the text is quickly inputted to the device via the Terminal for Screen reader, and your Braille Sense returns to sending/receiving information to and from the connected device.
"Terminal Clipboard" can also be useful for transferring text from a document or e-mail in your notetaker, to a document or e-mail you are creating on your connected computer or SmartPhone. As the "Terminal Clipboard" is a standard edit box on the notetaker, you can paste text in to it from the notetaker's clipboard. (see the sections of this manual regarding selecting text as it applies to supported programs such as the Word Processor, E-mail, Web Browser, etc.)
To send text on the notetaker's clipboard to your connected device via the Terminal for screen reader, do the following:
1) While in Terminal Mode, press "Space-Enter-I (dots2-4)" to activate "Terminal Clipboard".
2) Press "Enter-v (dots1-2-3-6) to paste the text from the notetaker's clipboard to the edit box.
3) Press "Enter-S (dots-2-3-4)" to send the text to the computer or i-device via the Terminal for Screen Reader.

13.12 Using Macros

Macros allow you to automate functions of the Braille Sense for ease of use and efficiency, especially in cases where you perform a similar action often. For example, you may wish to set a macro to open a set of programs and documents when you come to work each morning. Or, perhaps, you want to set a macro to automate insertion of text and formatting of a document. You may even want to create a macro to automatically set an alarm for 6 in the morning the next day.

13.12.1 Recording a macro.
To create a macro, you simply ask the unit to record a set of functions as you do them, and save it. To begin recording a macro, press "F2-R (dots-1-2-3-5)" from anywhere on the unit. Perform all the functions you wish to automate later, then press "F2-R" again to stop recording. For example, if you wish to set a macro to set an alarm, press "F2-R", go to the Utilities menu, and the Wake Up Alarm function. Go through the process of setting the alarm. After you have pressed "Enter" to complete the alarm setting, press "F2-R" to stop macro recording. You are asked to enter a name under which to save the macro. Type it in the edit box, and press "Enter". If you have made a mistake, and do not wish to save the macro, press "Space-Z (dots1-3-5-6)" to cancel saving the macro.

13.12.2 Executing a Macro.

To execute a previously created macro, press "F2-E (Dots-1-5)" from anywhere on the Braille Sense. You are prompted for the macro name, and the last macro you created is automatically displayed. To execute a macro, type its name and press "Enter". The unit announces, "Executing macro, please wait,,,". The macro takes several seconds to execute as it must perform all the functions you previously recorded. When the macro is finished running, you are placed in the position you would normally be placed in if you had performed the functions manually. For example, if you set a macro to open your e-mail and check for new mail, when it has finished executing, you are placed in your inbox with the focus on the first unread message.

13.12.3 The Macro Manager

The "Macro Manager" allows you to execute and manage macros you have previously created. The "Macro Manager" is located in the "Utilities" menu, just above the "Upgrade" option. To open the "Macro Manager", from the main menu, press "U (dots-1-3-6)" to open the "Utilities" menu. Navigate to "Macro Manager" and press "Enter" or press "M (dots-1-3-4)" from the "Utilities" menu to quickly jump to and open the "Macro Manager. You can also open the "Macro Manager" from anywhere on the unit using "F2-L (dots-1-2-3)". 
The "Macro Manager" dialog consists of the following items: Macro Name List, "Delete Macro", "Rename Macro", "Execute Macro", and a "Close" button.
The Macro Name List is a list of all the macros you have created. To execute a macro, press "Enter" on the macro you wish to execute, or Tab to "Execute Macro" and press "Enter". As previously described, you can also execute a macro from anywhere on the unit by pressing "F2-E". To delete a macro, navigate to the macro you wish to delete in the list, Tab to "Delete Macro" and press "Enter". You can also press "Space-D" when the macro you want to delete is focused. You can rename a macro by focusing the macro you wish to rename, and selecting the "Rename Macro" option. When you press "Enter" on this option, you are placed in an edit box in which you can type the new macro file name, with the current name displayed. To rename the macro, edit the current name or type a new one, and press "Enter".
