_ (the underscore) is the placeholder for exactly one character.
% (the percent sign) is the placeholder for no, one or more than one character.
%% (two percent signs) is the placeholder for no, one or more than one character, but not for blank space (so that a search ends at word boundaries).

At the beginning and at the end, these placeholders are superfluous.

An anonymous commentary on the Almagesti minor (C.1.3) with reworked proofs. The only known manuscript was copied around 1300, perhaps in the region of Padua, where it appears to have been glossed in or shortly after 1368. As it stands in this copy, the work is incomplete, ending abruptly in II.35 due to missing folia.
