Involuntary, unintentional or unconscious actions aren't Karma, because willing is an important factor in determining Karma.
All good and bad action constitutes Karma. In its ultimate sense, it means all moral and immoral choosing.
Any kind of intentional action whether mental, verbal, or physical can be regarded as Karma.
Karma covers all that is included in any phrases, thoughts, words, and deeds.
Avoid thieves, liars, slanderers, and malicious perverts.
