Some days ago, I updated all my Emacs instances to the current version 25.4. After doing so and updating all the packages, I noticed two things:

  1. helm-M-x did not work
  2. I forgot how I could start the IDE inside of Emacs I used to code my masters thesis.

After a short time of experimentation, I came to the following conclusions:

  1. It seems that helm does not replace the standard M-x keybinding by default anymore, so
    I had to set that manually via (global-set-key (kbd “M-x”) ‘helm-M-x).
  2. Digging through some Google search results, I remembered the command to start my IDE inside of Emacs: ecb-activate. This start the Emacs Code Browser, which provides me with a nice sidebar of folders, files and functions for my current project as well as some handy shortcuts for navigation said project.

This is just a small reminder for myself in case I should forget again how I invoke the code browser. 😉
