15.7.2 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". 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" 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 from your notetaker: 
1) Press "Space-Enter-I" to activate "Terminal Clipboard".
2) Press "Enter-V" to paste the text from the notetaker's clipboard to the edit box.
3) Press "Enter-S" to send the text via the Terminal for Screen Reader.
