You can set the button to launch onenote with a command line switch like this “onenote /audionote”, which starts a recording on the current OneNote page. You can also add the “/ filename” switch to specify a particular section to put the recording in. If Onenote is already running, trying to launch a new onenote this way does not actually launch a new onenote – it just attaches to the currently running Onenote.
