How can I make PowerPoint interactive in presentation mode?

Chirag Dalal has an example of how to move shapes during a show here:

http://officeone.mvps.org/vba/mousemove\_shape.html

As David's mentioned, in order to type into a shape during a show, it would have to be a text box control (Developer tab | Controls ... if you don't see the developer tab, you'll need to customize it onto the ribbon; it's not there by default)

Alternatively, you could write something like the aircode below and assign this as the Run Macro Action setting to any shape you want to add text to:

Sub AddText(oSh As Shape)

Dim sTemp As String

' Pick up any existing text

' in the shape so we can use it

' as the default text in the next step

sTemp = oSh.TextFrame.TextRange.Text

' Get the new text:

sTemp = InputBox("Talk to me", "Say something", sTemp)

' If there's any text, apply it to the shape

' To remove text from the shape, enter just a space

If Len(sTemp) > 0 Then

oSh.TextFrame.TextRange.Text = sTemp

End If

End Sub

I'm not up on the latest in PowerPoint 2010 so they might have added something, but in earlier versions, you would need the control toolbox to include text boxes that you can type into during slide show view. Dragging shapes around has never been a possibility in slide-show view, but you can use either motion animations or VBA to get them to move. For the text question, have a look here:
