 ## Speech preferences
 
+Use Cthulhu+Left/Right to select a quick speech setting and Cthulhu+Up/Down
+to adjust it. These changes follow you across windows, including application
+profiles, for the current session. Cthulhu+Control+Shift+S saves the choices to
+the global profile. Switching windows does not save or discard them. Applying
+preferences replaces the temporary quick speech choices; restarting discards
+unsaved changes. Saved application overrides still apply on the next startup.

 Speech preferences let you adjust rate, pitch and volume directly, without
 first disabling a default checkbox. Unconfigured values display Speech
 Dispatcher's defaults when available, or rate 50, pitch 5 and volume 5.
