 # cursor-lang
 
 The WPF application displays the keyboard layout at the cursor
+
+The app requests administrator rights on startup. Windows does not deliver
+keyboard input to a low-level hook while an app of a higher integrity level
+holds the focus, so without elevation the Caps Lock hotkey would silently stop
+working in Task Manager, Registry Editor and anything else started as
+administrator. Note that a plain shortcut in the startup folder cannot launch an
+elevated app — use a Task Scheduler task with the "highest privileges" flag.
