抱歉回复这么晚。就 TeX 而言,有一个可以使用的命令:
\NumericCallers{f}(或 {x})。然而,它似乎只有在没有定义任何“列出”的引用标记时才有效,而从用户界面来看,这似乎是不可避免的。在一个项目中,我看到:
\AutoCallers{f}{*,†,‡,¶,§,⁜,⁑,※,⁂}
\AutoCallers{x}{a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,θ,u,v,w,x,y,z,ʒ}
在 .tex 文件的第 170 行左右,这远远早于包含 ptxprint-mods.tex(大约在第 488 行)。
因此,我们可以“取消设置”自动引用标记列表,然后数字引用标记应该就能正常工作:
\expandafter\let\csname callers-x\endcsname\relax
\NumericCallers{x}
它确实有效:

但是(至少在不更改字体的情况下),在我看来,这些引用标记有点令人困惑:

(如果你想覆盖脚注,请将 callers-x 和 {x} 更改为 callers-f 和 {f}。)
Sorry for such a late reply. In terms of the TeX, there is a command that can be given:
\NumericCallers{f} (or {x}) However, it only seems to be effective if there has not been any ‘listed’ callers defined, and that seems to be unavoidable from the user interface. For one project, I’m seeing:
\AutoCallers{f}{*,†,‡,¶,§,⁜,⁑,※,⁂}
\AutoCallers{x}{a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,θ,u,v,w,x,y,z,ʒ}
around line 170 in the .tex file, which is a long way before ptxprint-mods.tex is included (around line 488).
We can, therefore, ‘unset’ the list of autocallers, and then the numeric callers should work:
\expandafter\let\csname callers-x\endcsname\relax
\NumericCallers{x}
And it does:

But (at least with no change in font) the callers end up a bit confusing, if you ask me:

(change the callers-x and {x} to callers-f and {f} if you want to override footnotes.)
