How to use different page orientations inside one document

Select pages or paragraphs that you want to change to Portrait or Landscape orientation.
    2.    On the Page Layout tab, in the Page Setup group, click Margins.

    3.    Click Custom Margins..., in the bottom of the list.
    4.    In the Page Setup dialog box, on the Margins tab, choose Portrait or Landscape orientation.
    5.    In the Apply to list, choose Selected text:

    6.    Click OK.
NOTE: Microsoft Word automatically inserts section breaks before and after the text that has the new page orientation. If your document is already divided into sections, you can click in a section (or select multiple sections), and then change the orientation only for the sections that you have selected.

Diameter symbol in MS Office (1997-2003)

Before all, select the Symbol font, then access the insert symbol menu. In the lower right corner will be the diameter symbol (not the awkward Latin-1 crossed O).

You can change the font afterwards, but it is possible that this symbol graphics is available or unavailable with certain fonts (!)

espace et tiret insécable

ne cherche pas (en tout cas pas comme dans Word...).
Pour l'espace insécable, utilise la combinaison de touches : <Alt>0160 (sur
le pavé numérique)
Pour le tiret insécable : <Alt>0173

ou alors, si tu veux faire plus simple, appuie sur <Maj><Entrée> pour forcer
le changement de ligne et faire passer les mots que tu veux garder ensembles
à la ligne suivante.

PDFCreator Letter Paper Default

The settings are hidden away in a different part of the Control Panel -> Printers & Faxes.

• Right click on the PDFCreator printer in the Control Panel.
• Go to General tab -> Printing Preferences button -> Advanced button
• Change Paper Size from A4 to Letter.
• These are Windows-based settings. You may need to follow previous posts' advice about setting the page size within PDFCreator's options.

Note: Confusingly there is an Advanced tab of the printer properties with a similar screen called Printing Defaults. Letter is already the default page size, but obviously that doesn't work!
