-**Note 1:** More information about these keys can be found [here](https://msdn.microsoft.com/en-us/library/windows/desktop/dd375731.aspx).
+**Note 1:** An easy way get the name of a key is to run the client with the argument `print_keys` (`inputshare-client.exe print_keys`). This will open a small window that shows the name of the last pressed key.
 
-**Note 2:** Not every key in this list will work, it just won't cause the program to crash when reading the config.
