I'm trying to find information on what this RunCommand action is supposed to do. I thought it would select the entire column based on where the cursor is located. But all I can get is that this command or action is not available now.
Theoretically, it should work in a table, query or form in DataSheet view, but others have also reported that it doesn't work. Apparently an oversight by Microsoft... :-(
