Question

Hi, I noticed that

This renders OK!

but that:

Invisible Exclamation Marks

occur when more than one consecutive ! is typed in any heading level. Since multiple exclamation marks render OK in plain text, I wonder if this is a feature of some sort. Why don't they render in headings?

Answer

The first ! is a replacement for <nop> but I can't explain why this makes the second ! disappear. Especially because both ! are shown in the table of contents (%TOC%)

Hidden Heading

he doesn't have !! before the header text, it's after! please file a BugReport

No, this is a feature, not a bug. Sometimes it is useful to add some content to a topic that should not show up in the TOC, e.g. an edit icon (for composed docs with includes).

I so hope you are making a joke here Peter!!

No, this is useful, and in fact used in at least two TWiki installations I have seen. It is also documented as such in TextFormattingRules: "Any heading text after !! is excluded from the TOC"

Example usage:

Example heading with excluded icon

The following would be placed in WebPreferences:

• Set EDITICON =

Two consecutive ! are bad practice anyway.

i'd agree that it sounds useful - but its not what you would call intuative :O

Just for the record I already filed the bug report under InvisibleMultipleExclamationMarksInHeader before Peter made his comments. I would say that the support question is answered by Peter's reply and any continuation is done in Codev?
