Leveraging External Programs
Although KDevelop is a so-called Integrated development environment, it will never contain all features that you may want to use, and the capabilities of its editor will never suffice to perform often-used text processing tasks. As a genuine program, KDevelop contains several possibilities to start external programs, plugin external programs to work on files, or use external filters to process the content of the editor.
The most general and simple feature of this kind is the tool menu, which you can freely configure. This is done in the Settings Configure KDevelop.... dialog under External tools.
Other tools will be discussed in the chapter Plugin Tools.
