I am using the Ranger file manager, and I like it quite a lot. I often use the :mark command to select specific items in the current folder. And now comes the problem: Once I am done doing whatever I wanted with them, I don't know how to unselect the items again in a batch. So I usually :mark one specific file and then press Space to clear the selection. Sometimes I return to a folder days after still finding certain items still marked/highlighted/selected. I couldn't find an "unselect_all" command yet. Am I missing something?
