Why doesn the delete key work on the keyboard?
Many students do not understand the purpose of noun-verb selection, so they turn off this options. Noun-verb selection allows you to pick objects first and then select the commands.

To fix the problem, type “PICKFIRST” on the command line and enter the value of 1.
