Package "gedit"

official text editor of the GNOME desktop environment
gedit is a text editor which supports most standard editor features,
extending this basic functionality with other features not usually
found in simple text editors. gedit is a graphical application which
supports editing multiple text files in one window (known sometimes as
tabs or MDI).

gedit fully supports international text through its use of the Unicode
UTF-8 encoding in edited files. Its core feature set includes syntax
highlighting of source code, auto indentation and printing and print preview
support.

gedit is also extensible through its plugin system, which currently
includes support for spell checking, comparing files, viewing CVS
ChangeLogs, and adjusting indentation levels.
