In Fedora 10, the standard KDE text editor kedit is not present. The default text editor in KDE is kwrite instead of kedit. To open kwrite you can go to “Fedora Menu > Applications > Utilities > Text Editor (kwrite)”.

Alternately you can press Alt+F2 which opens run dialog in which you can type kwrite and press Enter key.

Alternately you open Fedora Start Menu and type kwrite in the search box.

Otherwise you like tabbed editors, you can use gedit which is GNOME desktop based text editor.
