Keystroke: ⌘ + C
Copy is used to places the selected (highlighted) text into the so that you can duplicate it. Use Edit: Paste to insert the text elsewhere in DBT or into another application. The text remains highlighted after you have given a command, (e.g. Ctrl + c to copy) until such time as you use a navigation key such as one of the arrow keys.
Note: When pasting into another application, take care. Markup elements such as DBT Codes will not be pasted to other applications. Likewise, if you copy and paste from a document in Braille view, you will not necessarily see the braille font on the screen when you paste.
