\paragraph{Why WYSIWYG-editors are slow.}
WYSIWYG-editors are popular because the learning curve
is small, but it has low productiviity and forces you
to coordinate your eyes with your hands in text editing.
So if you are in computing for the long-haul,
or do any significant amount of text editing,
I suggest that you invest some time to
learn a powerful non-WYSIWYG editor.
Just as you are told to learn to touch-type in high school,
you will find this investment highly rewarding.

Touch typing frees your eyes to roam.  Also, keyboard
entry editors immediately allows you to enter macros
and iterative operations.  E.g., if you want to delete
an 50 lines, you should not have to count up to 50
(this is slow and calls for eye-action).  You should
be able to type "50d" and be done with it.  
That is exactly what keyboard entries allow you to do!
In short, most common tasks can be done with a few key
strokes without eye-coordination.

Two such editors are VI and EMACS.  EMACS has its
advocates, but I prefer VI-derivatives such as GVIM.
In particularly, I recommend the free "GVIM" which you
can download from the web.
