Activated abilities contain a colon. They’re generally written “[Cost]: [Effect].” Some keywords are activated abilities and will have colons in their reminder text.

Suppression Field’s ability doesn’t affect static abilities, triggered abilities, or mana abilities. (A “mana ability” is an ability that produces mana, not an ability that costs mana.)
