It isn’t even *convenient.*
You know you’ve spent too much time coding HTML by hand and too much time writing things destined to be in Standard Manuscript Format when you reflexively type <i> instead of hitting Ctrl-I for italics.
(For those not familiar: SMF requires, among other things, the use of underlining instead of italics. So I almost never use italics except online, when I’m typing the HTML tags for it. Then I do it in Wordperfect and wonder what’s wrong with me.)
