I always prepare my material in a real text editor, until I’m completely satisfied with the content, before I risk dumping it into PowerPoint or another terrible editing environment. I mean, 99.9% of presentations contain bullet points and it’s still a mystery what will happen the next time I type a key: will there even be a bullet in front of the next line of text, will it just invent a new line spacing different from the previous bullet, etc.?
Then, as if to punish me for having the audacity to save time composing text outside of Office, its Paste mechanism utterly destroys text in ways that almost seem malicious.
I end up having to find and disable so many settings just to restore a reasonable set of behaviors for stuff like Paste (bad defaults).
