Value List without text but only icons

Perhaps, with some non-printing characters, but I have severe concerns about the usability element here...  What if the value list item is shown without the icon?

Hi, it worked with the following Key combination: ctrl + -

Well, if the icon is not shown then you have no idea wich item is selected. But that is not a problem for our use case.

If it is to be used in a column in a View I prefer to have the text there as well but then just narrow the column to only show the icon for daily use. Then you can always get the text value if needed for explanation.
