Thanks for the +rep. Unfortunately, by default you can't see those abilities in the object editor. However, you can see them in the AbilityData.slk file, which is inside the War3Patch.mpq. Path: War3patch\Units\AbilityData.slk. If you open it with a notepad, it's possible see all existent abilities in the game, and also make them appear by modifying the K field to 1. For example: The locust ability (Aloc) has the field C;X5;K set as 0 (C;X5;K0), then you just have to change that 0 to 1. (C;X5;K1). There's also SLK editors in order to edit those files, but I don't use them.
