Place cursor in Terminal on "Go To Terminal"

When the shift-apple-T hotkey is pressed to "Go To Terminal", the user still needs to click inside the box to place the cursor there. Please place the cursor in the terminal so the user can just start typing.

Start by tracing the Shift-Apple-T “Go To Terminal” action and its terminal focus handling; the issue does not name a file or test. Done means invoking the shortcut places the cursor in the terminal so typing works immediately, with a regression check if the project has one.
