I usually apply additional attributes (such as RED font color, and a script font) to emphasize the hidden text. You just have to be sure to turn OFF the 'hidden text' option, in the 'Open Office writer' tab, when printing a 'student' version, because the last printing settings are apparently saved with the document!!

You can create a 'teacher's key' PDF by 'print > printer/or/PDF Creator of course, the answers are still stored, and visible when desired, in the oO document. Thus, you can create a student version without the answers, for example to e-mail out. Sadly, to create a document version WITH the hidden text included & visible, you have to resort to an external PDF generator (such as PDF Creator - a very useful utlity) that PDF document WILL include the hidden text. However, in printing, export to PDF will NOT include the 'hidden text' I've tried all sorts of settings. To save a version WITHOUT 'hidden text' you can simply Export as PDF. You can easily display the 'hidden' text with 'View non-printing characters' (Ctrl-F10 will toggle ON/Off) very useful. I am doing something similar: student worksheet, with the solutions/answers in 'hidden text' (oOffice: Format > character > 'font effects' hidden) Would you know of a method of actually including the Hidden Text when exporting to PDF from Open Office? The only way to include it is to disable the hidden text - by Highlighting text and unchecking Hidden in Format ->Character->Font Effects Tab.

There appears to be no option in Open Office to display the Hidden Text when printing or exporting to PDF. However, in Open Office when File ->Print Settings -> Options and select Hidden checkbox under section 'Contents' the Hidden Text is not displayed when print previewing / exporting to PDF. Once this is selected and converted to PDF using Adobe the Hidden Text is included.

In MS Word this is done by selecting File ->Print->Options and selecting the Hidden Text Checkbox under section 'Include with Document'. There is no option available to enable the Hidden Text when selecting File -> Export to PDF in Open Office Writer. Internal PDF's can allow this hidden text to appear for internal use. This is working fine as hidden text does not appear by default. For security reasons hidden text should be kept hidden on generated PDF's that are intended to be publicly accessible.
