Importing the accompanying key map file will add two custom actions called: Custom: Decrease volume of selected tracks 1dB Custom: Increase volume of selected tracks 1dB These might be more useful to you than the SWS actions OSARA uses, because these custom actions will work on tracks, grouped tracks and the master track. The SWS actions OSARA uses don't work on the latter two. However, there are some trade-offs you should be aware of. These custom actions will only speak the adjusted volume of the most recently touched track, even when multiple tracks are selected/being adjusted. They also can't prepend the word "track" to the first adjustment like OSARA usually does. The custom actions are already assigned to Alt+Shift+Down and Alt+Shift+Up respectively, as they're intended to be drop-in replacements. They were made using: OSARA: Mute next message from OSARA Track: Nudge track volume down Repeat that combination 19 times Track: Nudge track volume down The one that increases track volume just substitutes Track: Nudge track volume up instead.
