Sublime Text (https://www.sublimetext.com) has been my goto for years.

In my experience, it is very lightweight, opens large files quickly, and the multi-cursor support is second to none.

I often use it "between" apps, meaning I use it to inspect and massage texts before pasting it somewhere else (e.g., logs from Grafana to JIRA, etc.).

With a few customizations and a few "Packages", it can even function as a (very) basic IDE. These days, it is my primary golang IDE.
