There is a keyboard shortcut called "write automation" (TDM-systems only): apple + / for the currently active parameter (the one visible on the track's data view) and apple + option + / for all automation enabled parameters. I have sometimes used it to automate faders, pans, send levels and eq's. However, yesterday I wanted to use this with Autotune's "keyboard" parameter, but it did not work out...
Neither did recording automation in "write mode"...
