     Impact _ Annoying'
     There seem to be a variety of nonserious TEDIT formatting'
problems when it comes to making deletions in contexts where there are'
subscripts or superscripts.  Fortunately, all are illusory and will go'
away on Redisplay or for the more resistant cases, Shape of your TEDIT'
window.'
     Some examples.  We use ^ and ! to indicate that the following'
char is SUPERSCRIPTed or SUBSCRIPTED 4 points.  (All examples only'
involve chars F, O, B, A, R, 1, & <CR>.)'
(1) Delete <CR> in'
	FOO<CR>'
	BAR!1'
FOO vertically aligns with subscript 1.'
(2) Delete 1 in'
	FOO<CR>'
	BAR!1'
Bottom part of FOO gets chopped.'
(3) Delete <CR> in'
	FOO!1<CR>'
	BAR'
BAR vertically aligns with subscript 1.'
(4) Delete 1 in'
	FOO!1BAR'
Top part of FOOBAR gets chopped.  Must Shape TEDIT window to get'
correct display.'
(5) Delete 1 in'
	FOO<CR>'
	BAR^1'
Bottom part of FOO gets chopped.'
