The text console screen reader Speakup for Linux has the ability, using the modifier key plus keypad enter by default, to turn off the realtime speaking of text that appears or changes on screen. This is similar to the Orca+S key, which turns off speech, except that in Speakup, the review keys on the keypad still speak the text at the review cursor as they do when speech is not turned off. A similar feature for Orca would be extremely helpful, especially in a text terminal where text is constantly changing or scrolling, and the user ownly wishes to periodically use flat review to look at the output while speech is otherwise turned off. It would also be beneficial to have a temporary silence feature similar to Speakup's keypad enter feature, where speech is silenced until a key is pressed, at which time, speech resumes. Such a feature would make it no longer necessary to fully turn speech off in a constantly chattering text terminal or other constantly changing environment. I realize that the Orca key and right control key seem to adjust verbosity of changing objects in some cases, especially if the text that changes is rather small, percentages in a terminal window and download/upload speeds in Deluge for example, but a full stoppage of all speech until a key is pressed would be helpful in situations where output is constantly scrolling, for example during apt-get update or similar.
