Whow! This is really cool, especially for people that do not know the different commands by heart -- like me. I often know there's a command that's spelled somehow like X but I don't exactly remember. Your patch seems perfect for that situation. :-) Keen on seeing it in a future release. Thanks in advance. Did someone suggest it or was it your very own idea?
