I write Go code almost exclusively. I don't have a video demonstrating it, but you can read http://jfloren.net/tools.html for more information about how I use acme, and watch https://research.swtch.com/acme to see it in action.

Here's a few key points:

* Select text & middle-click it (or just select with the middle button & release) to execute a program. I just keep a file full of common commands open at all times and fire them off as needed.

* The "acmego" tool automatically formats my Go code & adds imports as needed whenever I save. The "A" tool can find the definition of any function/type/variable I'm looking at and open the source file to an appropriate line. (yes I know these things are available in other editors)
