I would suggest anyone who did not know this go back and read through the Active Help guides, just incase there are any other missed qol tid bits. This was covered fairly early in those when controller was selected for input, appearing when you are first introduced to being the golden pizza deliveryman of lore in msq2.

The active help guide is different depending on which input you have selected at the time, and is very easy to turn off intentionally or not at the very start. I also do not recall the kb/m version mentioning this shortcut at all, just clicking on the item.
