Change / jump back to previous language; «jo'au lo prula'i».
This shortcut jumps back to the previous language set by either bau'o or jo'au. This is like ‘cd -’, not ‘popd’; like a jump and not a call in assembly. (Technically two stacks can be maintained by other mechanisms.). This might not be a commonly used feature, but like Identity, it allows zoi'o to switch back after being terminated by li'u. See also: jo'au'i (push current language), zoi'o (quote and change language).
