Sure I already told you to apply your solution if you're more or less
sure that it'll work, I was just discussing in general.

Why not just deactivate the deleteEmtpyParagraphMechanism if we are
selecting? Just don't call it if we see we have a selection, IMO this
would be the best solution and it would also permit to start a selection
from a empty paragraph without the need to enter dummy chars just for the
selection.

I owe the government $3400 in taxes. So I sent them two hammers and a
