Information:
Scintilla is a free source code editing component. Along with features commonly found in standard text-editing components, Scintilla includes features that are especially useful when you're editing and debugging source code.
These features include:
Support for syntax styling
Error indicators
Code completion
Call tips
The selection margin can contain markers like those used in debuggers to indicate breakpoints and the current line.
Styling choices are more open than with many editors, allowing for the use of proportional fonts,
bold and italics, multiple foreground and background colors, and multiple fonts.
