Here is a great video demonstrating it’s powerful features and how it can save you a ton of time! It is highly customizable (but there is a learning curve to making the tweaks to your user settings. I love it because I have the property files (which provide IntelliSense & syntax highlighting for ~80 languages)
The editor is free and can be downloaded from here. If you’re using AutoHotKey you can get SciTE4AutoHotkey built by fincs here.
One of my favorite things about SciTE is that it is highly customizable! If you have favorite commands you frequently use it is really easy to add them to Customize your SciTE context menu.
