Why can't you undo after saving?

[acapella]

Hi,

Here is a question that has always puzzled me: Why in the world is the undo
history deleted every time you save a presentation in PowerPoint?! It
doesn't make sense to me... Is it a bug or a "feature"? I don't find that
feature in Word or Excel....

Hi,

To me, it's a feature. At some point, you decide you want to save and move
on. So PowerPoint saves, and you move on. If all your undo's are still
available, then what happens? Do you send a file to someone else, and they
can undo your editing as well, because it is still available? Not something
I'd be keen on. Plus the bloat of file size having that information there
anyway.

I think this is BS actually. I was coping and pasting a line of text into an existing text box in Powerpoint (to make a list), and every time I hit return to generate a new line (which expanded the vertical size of the textbox) then copied a prior line of text then put the mouse under the existing text and hit ctrl-V to paste, it replaced the whole of the existing full-page textbox with the single line of pasted line (I have no idea why, probably, unlike MS word, textboxes do not create carriage returns unless they are used immediately, DESPITE EXPANDING THE VERTICAL SIZE OF THE TEXTBOX, and so it was inadvertently selecting and replacing the whole textbox), so every time I tried the above, I had to then ctrl-z to undo the paste. On about the 5th try, in my frustration, I hit ctrl-s instead of ctrl-z by accident and poof ! the whole page of text all gone forever.

What you need is a .ppxd extension (powerpoint draft), then a menu option for "Save-publish" or "save-final" that generates pptx and strips out the undos, and not have a keyboard shortcut for this.
