Karn's first ability affects only artifacts on the battlefield. Activated abilities that work in other zones can still be activated.
Activated abilities contain a colon. They're generally written "[Cost]: [Effect]." Some keyword abilities are activated abilities and will have colons in their reminder text, such as equip. Triggered abilities (starting with "when," "whenever," or "at") are unaffected by Karn.
