So questions/remarks: 1) What is the rationale for defining most accents as "postfix" operators? 2) The rules for determining the form and the operator dictionary make this two cases behave differently: - low line: <mover><mi>abcdef</mi><mo>_</mo></mover> (form = infix, so not stretchy) - overline: <mover><mi>abcdef</mi><mo>‾</mo></mover> (form = postfix, so stretchy) 3) Why is "check mark" a stretchy accent (or even just a mathematical operator)? Is it related to \widecheck (caron) or square root? -- Frédéric Wang. www.maths-informatique-jeux.com <http://www.maths-informatique-jeux.com> www.maths-informatique-jeux.com/international <http://www.maths-informatique-jeux.com/international>Received on Wednesday, 21 April 2010 10:28:06 UTC
