Hey there,
So if I understand correctly, You're trying to create a Macro which activates 2 Keys with a single Input which is LCtrl + Space activated While Pressed?
What I did was : Create new Assignment - Assign. Type (Macro) - Key (LCtrl) - In Macro window underneath the word Advanced, Click on the Icon with the 3 Vertical Dots - Add New Event (Add Event Window comes up) Type a Key (lmb click inside the adjacent box) LCtrl - Repeat Add New Event use (Space)
Now I chose LCtrl as the Keybind for the Macro Assignment which when pressed both LCtrl & Space will be your new Input, effectively changing a single Key to a Multi-Input command.
In the Advanced you can change the way this new Macro Assignment performs. There are more Advanced Options in the Profile List - Key Assignment (iCue Software), than there are in HW Key Assignment (Device On-Board Storage).
