+#### Wayland
+
+Due to a [an issue in Electron](https://github.com/electron/electron/issues/38288), the global hotkey will not work in all applications running under Wayland. In KDE it is possible to work around this limitation by adding this Kwin script:
+
+```javascript
+function toggleHeynote() {
+  var client = workspace.clientList().find((c) => c.resourceClass.toLowerCase() === 'heynote');
+  if (client) {
+    if (client.minimized) {
+      client.minimized = false;
+      workspace.activeClient = client;
+    } else {
+      if (workspace.activeClient == client) {
+        client.minimized = true;
+      } else {
+        workspace.activeClient = client;
+      }
+    }
+  }
+}
+registerShortcut('toggleHeynote', 'Toggle Heynote', 'Ctrl+Shift+H', toggleHeynote);
+```
+
+See the [KWin scripting tutorial](https://develop.kde.org/docs/plasma/kwin/) for instructions on how to install the script.
+
+Remember to enable the script in the KDE System Settings. It may also be necessary to go into the KDE System Settings and bind the "Toggle Heynote" key manually.
