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. Manascape Refractor won't gain triggered abilities (which start with "when," "whenever," or "at").

If Manascape Refractor gains an activated ability that's normally linked to another activated ability of the card it came from, those two abilities Manascape Refractor gains are linked for as long as that card remains on the battlefield.

Lands with a basic land type have an intrinsic activated mana ability corresponding to their basic land type. Manascape Refractor has those abilities, too.

If Manascape Refractor gains an activated ability that's normally linked to a non-activated ability of the card it came from, the ability Manascape Refractor has isn't linked to any ability.
