AutoCAD comes with a neat search feature. It is useful for those occasions when you don’t recall what the icon to find that command you’re looking for looks like or where in the ribbon it can be found. There is also the case with uncommon commands that do not have an icon in the ribbon. If you know what you’re looking for it’s quicker to search this way compared to searching in the help.
Note that how the search result is presented it shows you at which ribbon page the command is located. It lets you know where to find it next time.
