This is an updated version of the Clip Copy add-on for NVDA, initially created by Tyler Spivey in 2012. The original version of the add-on offered two keystrokes:
This version adds the ability to review the 100 most recent items spoken by NVDA, by default using the hotkeys Shift+F11 and Shift+F12.
Pressing Control+Shift+F12 will copy the currently selected item from the history, which is updated to be the most recent each time NVDA speaks.
In other words, Control+Shift+F12 still behaves as it did in the older add-on key F12, unless you've specifically selected an older spoken item to copy.
The beep on new text function has been removed.
