# Excellent tutorial video about Emacs Transient

Published on Sep 16, 2021, by Junji Zhi

I’ve been using Magit for a long time and haven’t thought about

Recently I bumped into this concept of Emacs transient and realized it is talking about Magit command popup window. I’ve using Magit nearly everyday and this UI is so useful!

After researching transient a little bit, I found this video from the Reddit discussion.

Adrien made an excellent presentation explaining how to build transient, and I don’t feel the need to go into details here.

A few things that widen my eyesight:

• How easy it is to make a major mode
• How to call shell commands, i.e., with (shell-command-to-string)
• How easy it is to make a transient command

Seeing the Emacs tricks step by step saves lots of my time of reading docs. Thanks Adrien!
