Gedit

Gedit (unsupported) is the official text editor of the GNOME desktop.

To start gedit in gnome. Select Foot -> Accessories -> Text Editor.

Gedit comes with well documented help. Open gedit and select Help (from the top right hand side) -> Contents.

You may find when you start gedit that there are no tools listed under the Tools menu. With the damtp install you need to select the tools you want. Open the help pages and learn how to load gedit plugins (Edit->Preferences->Plugins->Manager-> select the plugins you want). Once loaded, you can select the appropiate tool when you need it. One of the tools is a spellcheck.

You can use google to search for gedit tutorials.
