Hi Aditya, I know the syntax, my problem is about the options for the length of the arrow. For example \xrightarrow[big]{abc} gives a longer arrow than \xrightarrow{abc} According to different manuals also specific lengths should be possible. But they don't work. I think it's a bug. (because the example from a documentation doesn't work) Best regards, Johann On Fri, 2021-01-01 at 01:50 -0500, Aditya Mahajan wrote:

Hi there,

\starttext $\xrightarrow[50pt]$ \stoptext

doesn't work. But it should, right? In the manual

\starttext $\xrightarrow[50]$ \stoptext

is shown, but that doesn't work either.

The syntax is:

\xrightarrow{top}

or

\xrightarrow{top}{bottom}

I'm not sure which manual you are looking in to find a reference to the ability to add a specific dimension.

In the source I can only find named sizes of 'none', 'normal', 'small', 'medium' and 'big'. You can 'kludge' these by extending the length of the text using hard spaces. Alternatively there is \rightarrowfill which you might be able to put into a frame of the desired width?

\starttext $1\xrightarrow[none]{blah} 1$ \par $2\xrightarrow[normal]{blah} 2$ \par $3\xrightarrow[small]{blah} 3$ \par $4\xrightarrow[medium]{blah} 4$ \par $5\xrightarrow{~~~~~~~blah~~~~~~~} 5$ \par $6\xrightarrow[big]{blah} 6$ \par $7\rightarrowfill 7$ \par \stoptext

In particular the documentation https://dl.contextgarden.net/myway/matharrows.pdf shows exactly the example \xrightarrow[50] and the says the options are: none small medium big normal DIMENSION I'm sure I've seen the same options (i.e. including DIMENSION) in other documentations aswell, but I can't find them now. I assume this was removed with LMTX... is it possible to introduce it again? My problem is not to make the arrow bigger, I actually want to make it smaller. I have 2 long words above it, and so it's really long. I could use \clap{}, but then the spacing is gone and my 2 words clash with the text left and right of the arrow. So I want a small arrow with long text above it, but the spacing should be oriented on the text. Best, Johann

No, the change already happened in MkIV when Hans rewrote the arrows code.

And it's not planned to make specific sizes possible? Johann
