Copy to clipboard using the review cursor

[jteh]

Sometimes, especially in situations where some text can only be accessed with the review cursor (e.g. text consoles), it would be desirable to have a way to select text using the review cursor for copying to the clipboard.

Instead of the standard Windows method of selection (holding down a modifier while cursoring), I think setting start and end markers is more ideal. They require less finger twisting, less commands and less code modification.

This would be done as follows:

1. Move the review cursor to the start of the text to be copied.
2. Press NVDA+[ to set the start marker.
3. Move the review cursor to the end of the text to be copied.
4. Press NVDA+] to indicate the end of the text. This would cause the text from the start marker (set in step 2) up to the current position of the review cursor (step 3) to be copied to the clipboard.
