The so called Shirat HaYam, i.e. Shemot 15:1-18 has a long tradition of an ordering in an alternate 3-2 recursive columns with flow right, centered, flow left placement of the text.
This can be achieved on LaTEX either thru columns, may be just 3 and leaving once the center empty, or on each line placing the text in a flow cell, for example

modern Chumashim (German Schma Qolenu) help to learn and pronounce when reading the Torah with the set of BOLD for the A as O in QAMATZ or E sound instead of mute on SHWA.
Even may be rules for that (ex. COL) during the reading and correction for readers is very helpful in a Masoretic text to have these in order to be able toread perfectly accurate.
Looking for a general index of it in the Massorah Gdolah....

On SHemot 10:28 TNK has EL-Tosef where it should read AL-tosef by meaning and tradition. with PATACH
