Guideline Properties Dialog Box
This dialog box allows you to enter the exact position for the guideline. Type a value (for example "2cm" or "3in") and click OK. If you are creating a new guideline, clicking Cancel will stop a new guideline being created.
Tip
The units used for the guideline
position are the Page Units set for the document, see Changing
the page units. Note however that the units used on the rulers (and
grid) are set using the Grid
and Ruler Options.
