Sorry if this is not the appropriate place for this post, but it seems to be most proper. I was using kde desktop and there is one very helpful trick to select multiple files only with mouse - when the cursor is over an icon a circle with plus sign appear next to it if it is not selected, and respectively with minus sign if it is. By this way you can select files without to have to hold <ctrl> key pressed. A few days I saw this on a presentation(on a different subject, not about windows explorer) and there has theese circles too. I think this is some addon or plugin matbe, and I want it.
