Description: when we write an equation with Na^{+} or with _ or rsup or rsub there is an error (reverse ?) but not with Na^{+1} equation need a number but in chemistry, we need to write SO rsup{2-} rsub{4} without error the reverse ? is even printed, so it's very painful Steps to Reproduce: 1.insert equation 2.write Na_{+} Actual Results: reverse ? Expected Results: nothing, normal equation Reproducible: Always User Profile Reset: No Additional Info: Version: 7.0.1.2 (x64) Build ID: 7cbcfc562f6eb6708b5ff7d7397325de9e764452 CPU threads: 4; OS: Windows 10.0 Build 18362; UI render: Skia/Raster; VCL: win Locale: fr-FR (fr_FR); Langue IHM : fr-FR Calc: threaded
"+" is math operator expecting arguments. Na^{"+"} should be the correct way. I'd assume this is not a bug but usage problem.
This usage of text for operators (reserved words) is also described in LibreOffice Help - Entering Text at https://help.libreoffice.org/latest/en-US/text/smath/guide/text.html?&DbPAR=MATH use: Na^{"+"} or NA^{{}+{}} SO rsup{ "2-"} rsub{4} or SO rsup{{} 2- {}} rsub{4}
