Created attachment 145099 [details] The "Harpoon" symbol Currently in Math it uses vec (F) or widevec {F} to express a vector. However, in high school in Taiwan (not sure about other countries), we used "harpoon" (as attachment) upon one or more nodes to show a vector, and the "overrightarrow" (current vector symbol in math) is used to show a ray (an infinite line starting from a fixed point F toward a certain direction). It seems that currently only LaTeX supports the "harpoon" symbol. Can we add "harpoon" symbol into LibreOffice Math and formula editors for teachers to use on teachings and textbooks?
A valid request. I prefer personally a more generic solution, which allows the MathML attributes "accent" and "stretchy" to arbitrary characters.
