Planner-mode detectes MixedCase ?

[weber]

Hello everyone!
I'm having a really hard time trying to switch from Org-mode to
planner...
One thing that I would really like is to have this behavior described
on Wiegley's Commentary:

"Between the milestones are the bigger pieces of your plan. Name these
pieces using MixedCase? words, and you'll notice that Emacs colors and
underlines them for you."

So, when inside a muse file, just typing a mixed case word would
create a link, even if that page doesn't exist yet?
Adding links to existing pages could be also done this way?

Thanks in advance,
weber
