I made the mistake of using the select all columns feature in the Column Chooser to add all columns.  My table is now overrun with unwanted Text IQ fields…

Am I correct in my conclusion that there is no easy way to Unselect all columns and start from a blank slate?  

Alternately, I would be interested in a faster way of multi selecting columns in order to mass remove them from the view, rather than clicking through the cumbersome checkboxes in the Column Chooser and waiting while the view slowly refreshes between each change. 

Oh, and it also seems that Search feature within the Column Chooser does not work to find any embedded data fields (including text IQ fields) - correct? 

Thanks in advance for any suggestions!
