web editor with user tags

[Thomas Weiler]

Hello,

does somebody knows a good web editor in which you can define your own
user tags? The editor should also have a grafical layout like MS
Frontpage, where the user can click the website together.

My idear is the following:

I define a code segment:
<input name="test" id="test" onclick="setClick()">

Now I want a icon in the Button bar that you can insert in the html page
and then the own input box is shown at the position on the site.

Is there an editor who has this functionality?

Thanks for all answers.
