Is it possible to show rEFInd only when a modifier is pressed?

[Chris Osborne]

I've read through the documentation and can't see anything on this. I'd like rEFInd to start silently and then only rear its head if I press ctrl or space similar to grub does with shift when used in timeout = 0 mode. Is this possible? (MacBook Pro 8.2)
Many thanks.

Try setting screensaver -1 to have rEFInd come up with its screensaver enabled. You probably want to combine that with a reduced (from the default value of 20) timeout value.
