I made a screenshot of a typical post editor from another forum, i'm contributing member on several forums. The screenshot is self-explanatory: I am trying to use Mathematica as substiute for my other installed word-processing editors like MS Word (for writing letters to be printed out), MS Outlook Express (for creating quick'n dirty HTML documents), Notepad (for copy pasting temporary thoughts, notes), LaTeX (for creating docs mit math formulas) etc. But i am missing the marked functionality from the screenshot.

I am still a beginner, so maybe i am literally missing the functions 'indent a selected text' and 'stroke the selected word' and 'insert a (numbered or numbered) list', while they're hidden somewhere in the Mathematica GUI, please could you let me know? Thank you!
