I love mini find because it gives me instant incremental search type highlighting and doesn't take up much screen space. There's a couple of keys missing from the help I think Ctrl backslash cycles the "lookin" option, ctrl shift enter goes back to where you started.
A minor issue with ctrl shift enter is that the count "x of x" doesn't get updated but this is unimportant.
I would like to request that Ctrl Enter do "list all in next grep window and exit". Then I can use enter to step forward, shift enter backwards, ctrl shift enter go to start and ctrl enter - list all.
