As you may know, TextAtept is a cross-platform, open-source and minimalistic text editor that can be extended via Lua. Unlike other text editors, it uses buffer browsers instead of tabs. Among others, it has support for multiple languages, unlimited split screens, some code autocompletion features.
It is ideal for programmers and coders, since it has support for more than 80 programming languages.
Keyboard shortcuts, for an easier usage:
Ctrl + b to open a new buffer
Ctrl + Tab to switch between buffers
Ctrl + Shift + tab to switch to the previous buffer
