Option to execute all actions in directory instead of opening it

[Tunous]

Let's say that I've created a directory with few application launching actions. What I would like to do with that is to have an alternative action performed by some key combination like ctrl + <letter> or shift + <letter> to start all these applications automatically instead of opening blezz multiple times and selecting them one by one.

My preference for that would be to use shift + <letter> but I'm not sure how different letter case is treated.

Example

Main:
dir(a,Directory1)
dir(b,Directory2)

Directory1:
act(a,app1,app1)
act(b,app2,app2)

Directory2:
dir(a,Directory3)
act(b,app3,app3)
act(c,app4,app4)

Directory3:
act(a,app5,app5)
act(b,app6,app6)

For this content file, one could press these keys to launch corresponding applications:

A - launches app1 and app2 B - launches app3 and app4 b > A - launches app5 and app6
