Content Editor File Manager User Privileges


  • In the HTML editor, Enter key inserts a new paragraph and soft Enter (Shift+Enter key) inserts a line-break.
  • While editing La/TeX code of mathematical expressions, always use Shift+Enter for newline (if you need to make the code more readable).


[Important: Check detailed help for Text formats. ]

Content creation and editing is made simple by providing templates for various content types available @0space. Text in the input boxes provided in the templates can be formatted visually.

Templates are web-based forms consisting of sections or tabs for adding content, file attachments and internal or external links.

The forms will have input boxes (like Title, Body) for typing in relevant data. Some of the Text input boxes may offer you a Text formats selector to select Plain text or Full HTML from the drop-down options list.

Select Full HTML if you need formatted text. In Full HTML mode, using the buttons in the toolbar of the What-You-See-Is-What-You-Get (WYSIWYG) editor, you can easily format paragraphs, color text or background, create list, insert tables, images or Youtube videos, for example.

Preview button in the editor toolbar (icon with a magnifying glass) can be used to ensure desired formatting of content and mathematical expressions.

[This useful guide explains the features and the toolbar of the TinyMCE HTML editor.]

Tabs, embedding, popups

To insert Tabs, Accordion, IFRAME (with internal or external URLs loaded in them), existing content Node, use the markup tags and notations as given below: [See Detailed Compose Tips.]

  • Type the following text in content to create tabs (Don't copy-paste!)-


Title 1 (with <h3> header tag)

Text body 1 ...

Title 2 (with <h3> header tag)

Text body 2 ...


  • Use the word "accordion" in place of the word "tabs" in the above example to create an accordion (NOT accordions).
  • IFRAME is a way to embed content. For inserting an IFRAME with url as source, use

[[[<url> width=<w> height=<h> scrolling=<yes|no|auto>]]]

(replace strings within '<' and '>' by appropriate values.)

  • To insert a node's content in the current node ( = page), use 


((replace 123 by the id of the node to be inserted.)

  • To make a link open in a modal popup box, set class (in Insert/Edit Link dialogbox, Advanced tab) to 'pop' (without quotes).

Note that web page addresses and e-mail addresses turn into links automatically.


No nesting allowed for tabs and accordion, that is, you can't have tabs within tabs, or accordion within accordion.

If you need accordion within accordion, use Basic multi-step page type and put accordion (not tabs) inside steps.


For allowing you to insert mathematical symbols/expressions/equations in your content, this site uses La/TeX, which is rendered on your pages using MathJax. See this La/TeX help. Using La/TeX syntax, you can also achieve equation formatting, numbering, and referencing.

Remember to use "soft linebreak" [Shift+Enter] to break lines within "$" delimited expressions. "Hard linebreak" [Enter key] inserts an HTML paragraph element (<p>) and breaks the mathmode started by "$".

Also, NO '$' delimiter needed in equation reference - use "\ref{ref1}".

Help: Search

Site is indexed every 3 hrs. Any new content/term/user will appear in search results after about 3 hrs.

Search is case-neutral (uppercase = lowercase). A "word" means an alpha-numeric string of characters.

In content search, given word(s) are searched in the default rendering of node content [which would include the default rendering of all fields, as well as comments].

Hyphen(s) are omitted from words both for indexing and searching.

Minimum search word length: 3 character. Full string is matched. [Only in user search, substring is matched.]

AND Searches: simply type multiple words for results containing all words, AND is the default behavior.

OR Searches: for data that may contain one of a few words, but not necessarily all of the words, enter the keyword OR between each search word: "dogs OR cats" or "dogs OR cats OR birds".

Exclusionary Searches: filter for things that don't exist, put a '-' sign as word prefix.
