Introduction

My primary code editor as of Nov 18 2024. It is great. I will document all the tricks I know here that I may forget due to infrequent use. I use Spacemacs framework so a subset of the shortcuts listed here are from that framework.

• Update (20 November 2024): I switched to my own config, ditching Spacemacs.
• Update (24 November 2024): I switched from Evil Mode to Meow Mode.
• Update (18 November 2024): I switched from Meow Mode to Boon Mode.
