How do I map 'Ctrl + Alt + T' to bring up all existing terminals, rather than open a new terminal

Question

I'm trying to change the keyboard shortcut 'CTRL + ALT + T'. The behavior I'd like is to open all existing terminals in the current workspace, and open a new one if there aren't any.

I'm using several previous questions (1, 2), which work to varying degrees, but I'm currently stuck on getting the keyboard shortcut to work.

Here's what I've done so far. I went to Settings > Keyboard shortcuts, removed the existing shortcut for launching terminal, and added a custom shortcut:

Custom shortcut

Added an executable script to my bin named 'terminal':

Now, when I type 'terminal' into an open terminal, the script runs. But when I press 'Ctrl + Alt + T' nothing happens.

For the shortcut command, you should use an absolute path to the script. It probably doesn't search in ~/.bin directory.

Use

~/.bin/terminal

or

/home/adam/.bin/terminal
