There doesn’t seem to be a “reset to defaults” for everything, no. As far as I know, you either:
- limit the scope of the
set
rule; or - change the value to the original value.
Note: You can always make use of #include
for large part of text over several pages.
EDIT: You could always access the “previous” value and save it for future usage or reset purposes…
Current spacing : #context par.spacing
Beware of context returning content should you try to use this programmatically.
