Created attachment 55649 [details] Word 2003 file with an "eval" function There's a missing operator in Math, which is the "eval" symbol. It looks like a solitary "absolute" bar at the left of a variable, as it's shown in the attached .DOC file (which I'm not able to midify in LibO 3.4.4 on Kubuntu Linux 11.10, 64 bits). It *is* a very common operator in formulas, already present in the classical formula editor in word 2003, the formula editor of Office 2007 and I'm sure it's present in LaTex.
Thanks for bugreport Sorry, I can not find difference in attachment between msWord and Writer 3.3.4 and 3.5.3
(In reply to comment #1) > Thanks for bugreport > Sorry, I can not find difference in attachment between msWord and Writer 3.3.4 > and 3.5.3 Yes, when you open it, you could see it. It was resolved some time ago. Before that, Writer just crashed. But you will find the difference when you try to made that formula in Writer. It's impissible to do, because there isn't any "eval" symbol "Eval" consist in a long vertical line at the right of an expression, in this case, the "derivative of y with respect to x" is "evaluated at x = 1.3" and it's "equal to to 5.5". In Writer, theres only the possibility of writing both long vertical bars with the comand: "lline <?> rline " which indicates "absolute value", but no "evaluate at". The most similar thing is write in the formula "|" (WITH quotation. Whithout it, Writer recognizes another symbol, like a "v") which draw a small vertical bar. I'm attaching another document
Created attachment 61228 [details] As the 1º file, but with an example done in Writer 3.5.2. (the original file was build with MS Word)
I think I haven't made my self clear with this, and trying to explain my self better, I'va just discovered that LibO allows you to "evaluate" a function, but it's not shown in the "Elements" panel. If you wants to "evaluate" a function, as in the files I've attached: left none {d y}over{d x} right rline _{x = 1.3}=5.5 or even draw a lonely parenthesis, you should just wright: left none "expresion" right ) but the problem now is, that this option isn't shown in the element panel, so nobody without experience in LibO would ever figured out of how make it. (I discovered because I opened a .DOCX file created with Word 2007 and there was the magical word "none".) So I have changed the title
... So I have changed the title to something more specific: there should be a button in the Element panel, I have uploaded an image of the idea.

Thanks for additional information

I have changed the title, because the element panel will be deprecated. However, the option I'm suggesting to add is still missing.
