How to Assign CTRL-Super-T to BASH Shell I would like to assign said hotkey to the BASH shell.  How can this be achieved with native High Sierra capabilities?
Open automator, New > Workflow/ Service. 
Add "Launch Application" to the workflow:


Open System Preferences > Keyboard > Shortcuts > Services > Right click on the General > Show in Finder. Or alternatively navigate to /Users/you/Library/Services.
Copy the workflow there.
In system Preferences, it will show up and then bind a shortcut to it.
