You discuss three applications in your example... Sublime text is in your example screenshot, Finder and Forklift. Does Sublime Text have any reason to be in this discussion?
The way your macro shows is that when using ForkLift, if you press option-1, it will open the selected file (which in Finder) using Sublime Text. I can clearly see that.
If that's not what you want, you should explain exactly what you want.
Do you want your selection within ForkLift to open in Sublime Text??? If so, please state that.
Also, please post your macro here.
