is it possible to create a custom field checkbox where it will default to "True" if any field in a line is updated?

with script it will. not out of the box

would you know any articles I can take alook at which will help me do this? Thank you!

might be better to limit the scope...what precisely is the use case for triggering the checkbox to true?

@Al This can also be achieved with out of the box workflow. Just fyi
