In the example given by William the "new math cell" in text mode is not "live", i.e. it does not contain any actual commands (yet). The "special HTML" to which William referred is only an empty marker. After clicking Save from TinyMCE, the cursor is positioned at the newly created math cell and only then does the user begin to enter Sage commands. So tab completion, etc. in TinyMCE never arises. Of course it is tempting to allow commands to be entered instead the special HTML construct while still in TinyMCE and I think it might also be tempting (even necessary and desireable?) to allow more than one such special HTML construct to be inserted before clicking Save. I suppose that this design proposed by William is at least in part motivated by some ideas about what might be simple to implement as an extension of the current code base. But I have to admit that I find it just a little more "obtuse" for the user. It raises the obvious question about why actually command input might not be allowed inside TinyMCE. > > How about this: > > If you are in a text cell: > * ctrl-; splits the text cell, puts in a new math cell, and focuses on > the math cell. > > If you are in a math cell: > * ctrl-; splits the math cell, focusing on the second math cell > * ctrl-shift-; splits the math cell, inserts a new text cell between > them, and focuses on the text cell. > > I actually find that last case one that comes up often for me.

Besides these "hidden" key short-cuts, I presume that these same functions would be available from a mouse click? I also like you idea of splitting math cells in an analogous manner!
