File operations in Powermode without to first selecting the file

In Powermode, is it possible to do file operations without to first select(mark) the file?
IMO when my mouse cursor is over a file, it is already selected more or less.
Is there a way to accomplish that?

Now it sometimes happens that a file is unintentionally selected (and maybe out of screen) but the cursor is already somewhere else in the list.
And then a unintended fileoperation is done on some random file.

I know Detailed mode it is possible but I dont like the way Detailed mode works with selected files. Because when I move my cursor the selection is gone.

Also something strange in Detailed mode:
When I press Insert to select(mark) a file, the cursor moves 1 line down, without marking the file my cursor was on.
