 **Keyboard shortcuts …**| Ctrl+K, or Alt+O, K| Opens the global hotkey dialog (mute, volume, show/hide window, start/stop recording, remote-control commands, speak the status line).
 **Profile passwords …**| Alt+O, W| Lists every profile alongside its password, so you can view or change any of them in one place.
 **Manage named peers …**| Alt+O, N| Opens a list of every peer you've given a friendly name to, showing each one's machine name and where and when you last connected to it. Pick one and **Rename (Alt+R** , or F2) to change its name, or **Delete (Alt+D** , or the Del key) to forget it — deleting only drops the name, the peer still connects as normal under its machine name. See the peer-naming notes on the Connectivity tab.
-**Reset the default audio device prompt**|  Alt+O, R| Brings back the “use only the default audio device?” question if you previously ticked “Don't ask me this again” on it. See Following the Windows default audio device.
 **Enable / Disable Realtek ASIO**|  —| Only shown if a Realtek ASIO driver is installed. Lets you reverse the choice RemSound offered about disabling that driver (Realtek's generic ASIO driver tends to grab the wrong device and clash with your screen reader).
 **Install RemSound on this PC …** (or **Uninstall …**)| Alt+O, I (Alt+O, U once installed)| Turns the copy you're running into a properly installed Windows app — on the Start menu, with a desktop shortcut, and listed in Windows’ Installed apps — or removes it again. Once it's installed, this item changes to **Uninstall RemSound from this PC**. See Installing RemSound on your PC.

 ### Following the Windows default audio device
 
-At the very top of the **WASAPI outputs for received audio** list and the **WASAPI audio inputs to send** list there's a special entry: **Use Windows default audio device, follows Windows changes**. Tick it and RemSound uses whatever Windows currently treats as the default — the default speakers for received sound, the default microphone for sending — and, the useful part, it **follows that default on its own**. Make a headset your default and RemSound switches to it; unplug it and RemSound moves back, all without you touching the list.

Make a headset your default and RemSound switches to it; unplug it and RemSound moves back, all without you touching the list.
 
-It works alongside the specific devices: tick the default entry _and_ particular cards, and the sound plays out of (or is captured from) all of them at once. When you first tick it, RemSound asks whether you'd like to untick the other devices in that list, so you can choose to use only the default — with a “Don't ask me this again” option. If you tick that and later want the question back, use **Options → Reset the default audio device prompt**.
+Ticking it is **exclusive** : RemSound unticks every specific card in that list and locks them so they can't be re-ticked while the default entry is on. That keeps things unambiguous — in each list you're either following the Windows default or picking specific cards, never a mix. Untick the default entry and the specific cards become available again.
 
 Unlike the specific device ticks (which start fresh each session), the “use default audio device” choice is remembered between launches. It's safe to remember because it can never point at the wrong card — it always resolves to whatever Windows is using right now.

 Everything lives in the **Service** menu on the menu bar:
 
-  1. **Configure service profile …** — opens a small window with two tabs (Connectivity and Audio send) where you choose who to send to (plus a password) and what to send. There is no “send my audio” switch because the service always sends, and there is no audio-quality tab to fiddle with: the service always uses the settings that work best for live streaming (the Opus live-latency codec, small packets, locked to the audio clock), so it just sounds right. This is a separate profile from your normal ones and does not appear in the usual profile list. The **Additional options** button lets you turn the connect/disconnect sounds and the service's own log on or off.
