On Linux file manager, I think Dolphin (not sure right now, sorry) I can open Konsole just hitting F4. I would like to have the same on MacOS/Finder, openning Terminal instead. Is it possible?
I'm on El Captain.
Another great tool is cdto by Jay Tuley.
You could do it with a Service [a Service is just the best/simplest way to launch an app via key command, saves having to define plists etc]
If you just need to launch a default Terminal, very simply...
tell application "Terminal" to activate
Save [It will automatically save to the correct place for Services.
Open System Preferences > Keyboard > Shortcuts > Services. Your new service will be right at the bottom of the list.
If you need to open Terminal at your current location, that already exists as a built-in Service, just find it in the list, activate & supply a key command.
