Final answer:
The Edit Form command allows the modification of a form's layout and elements, with capabilities varying by software. Specific command line instructions like 'del :.b' for deletion and 'focus' for setting focus on elements can be used.
Step-by-step explanation:
The Edit Form command in a software application or development environment typically allows a user to modify the layout, structure, or properties of a form. The exact capabilities can depend on the specific software or development environment, but it often includes a combination of tasks such as deleting elements, adding new fields, changing the focus on certain elements, or adjusting the flow of user interaction within the form.
Using the command line, specific changes can be made to the form elements. For instance, the command del :.b might be used to delete a specific element, while the command focus could be used to set the focus to a particular field or part of the form. Accessing the command line can often be done through the "Tools" menu and the "General Controls" sub-menu.
