Ah, I see that now, Source Mode vs Live Preview. But either way you're not using a toolbar and mouse for basic formatting and it's not hiding invisible control codes from you as you edit like in a standard WYSIWYG editor. The sort of things that make Word documents so hard to edit.
Even in Live Preview mode, every character is visible when the cursor is in the area.
