Brahn’s Keyboard Addin is great.
I’ve used it for many years and it is one of the first things I add to any Clarion installation, along with Main Toolbar Extras, Editor Extras and Propert Grid Extras.
I also use the SharpeDevelop SelectWord addin.
The SharpDevelop SelectWord addin is included in the EditorExtras addin, with a few tweaks IIRC, but for anyone who wants to get it directly the original source is still available http://hem.bredband.net/dotnet/selectword/
