From this answer, one knows that the vertical space between the footnote line and main text can be accessed via \skip\footins
. But the examples in that answer all change this value globally. Is there some way to change this value only locally at one place? (A possible solution might be to change its value and then change it back, but I don't know how to restore the original value.)
The motivation of this question is the note I'm writing contains a lot of diagrams and page breaking can be a tricky issue -- on those pages with footnotes, using just \enlargethispage
doesn't look very satisfying sometimes, and it would be nice to be able to reduce the vertical space between footnote line and main text at these places.
