Here are two questions (or maybe one question, and a bug report) from my
note taking while reading the manual.

***** Best way to make next menu item?  M-Enter seems to work pretty well.
I'm not to happy with the way org-mode adds a blank line after a block
of text when doing C-S-RET from the entry line, and M-RET from the
block of text.  Do most of you have a blank line after your text
blocks, but before the next entry?  And, I just noticed that it
doesn't ALWAYS add the blank line . . . tres strange.  The blank lines seem
to have some correlation with having other blank lines after higher nodes.
It is VERY strange behavior . . so far, unpredictable to me :)

***** C-<RET> does not seem to do what the info page suggests.
It seems to go into a column selection mode.  Which, by itself, is
very useful, and I'll have to remember that.   I can't seem to find
the C-<RET> behavior anywhere (jump over the body, and add a new
heading at the same level. C-S-<RET> Does do what it is supposed to,
so, I guess a good workaround is C-S-<RET>, then backspace over the TODO.
