When you start KPresenter, the usual KOffice startup dialog appears.
Select
Screen
on the left then select the template labeled
Title
(highlighted in blue in the screenshot above) by
clicking on it. You can check
Always use this template
to
make it the default template.
Now click
Use This Template
. This brings up the slide
editor window, where you can view and edit the slides (and objects contained in
them) in your document. At the moment, we just have one slide, with one
object on it, which is a text box.
Double-click the text box. The cursor changes to a vertical bar to show
that you can now type some text and the background of the edited area
becomes grey.
Go ahead, type some text!
Click away from the text to de-select the text box when you are done
typing.
