Should we delete them? I don't think they would help to find the questions, also I've never met anybody being expert of headers.
I thought there was a page formatting tag covering all these things, but apparently not. Individual tags for every page element make no sense. However, an argument can be made for a page formatting tag (admittedly meta).
It provides focus for the question, like the printing tag. How to do anything would vary with each application. We don't have experts in page formatting regardless of application. But getting fancy with it in any application can take a level of knowledge many users might not have. Also, people sometimes use focus tags to screen which questions they want to look at.
It wouldn't be the end of the world to have a page formatting meta tag. The fact that tags for each page element got created and used indicates that people think in those terms, and want a tag of some kind. If we create one, all encompassing, page formatting tag and synonomize the others with it, at least we can move users in a more constructive direction. It would also discourage having these tags recreated if we simply delete them.
Suggestion in an attempt to provide some organization. There's no way to make this perfectly clean, but this kind of structure may tend to attract questions into logical groups:
text-formatting: use to encompass all things that deal with:
- the appearance of characters: text attributes (e.g., bold, italics, strike-through, super/sub-script, color), font size, character spacing, hyphenation, and the like.
- (Fonts): This is a closely related area, but we probably don't want to incorporate it because it is an entire subject area by itself. However, questions about things like applying an existing font could fit under text formatting.
- Formatting contiguous blocks of text (this will overlap with the next group): things like indenting, tabs, bullets and numbering, text wrapping within a column, page and section breaks, text margins and borders within a table or column, adjusting content to fit in a space or on a page, etc.
page-layout and page-formatting (synonyms): use to encompass all things that relate to positioning things on a page: headers, footers, margins, positioning objects, creating/modifying columns, linking text boxes and controlling the flow of text, wrapping text around objects, layers, tables, page layout considerations like mixing single and multiple columns, etc. This will overlap with the 3rd bullet, above, on contiguous blocks of text.
document-design and document-layout (synonyms): use to encompass all things that relate to the overall structure of the document: templates; global document formatting rules; features that apply to the entire document, like index, TOC, and page background; graphic design or theme (even if located on only one page); in some documents, linking text boxes and controlling text flow might overlap here.
