Cannot execute the specified command

What happened

The button, hotspot, or toolbar tool you clicked executes an @command or other action in a mode that does not support that action. This message appears, for example, if you click a tool that does not apply to the current view or that references an unsupported function, such as an unavailable Help file.

What you can do

Make sure that the action you try is appropriate for the current context. If the window has frames, try clicking a different frame.
