\vskipnextgrid, that moves to the next grid position. This may be enough under some circumstances. In other circumstances it may fail. So gridset is only one more step for grid setting not a complete solution.
If you have a distribution of gridset with an archive containing the files
doc/ doc/latex/gridset doc/latex/gridset/gridset.pdf source/ source/latex/ source/latex/gridset/ source/latex/gridset/gridset.dtx source/latex/gridset/README tex/ tex/latex/ tex/latex/gridset tex/latex/gridset/gridset.sty tex/latex/gridset/gridsetexample.tex
you may simply extract this archive at your local texmf tree (local TDS tree) that may be e.g. C:\localtexmf or /usr/local/share/texmf or /usr/TeX/texmf-local. On some systems you may ask for the local TDS tree using: »
kpsewhich -var-value=TEXMFLOCAL«. After extraction you should update your File Name DataBase e.g. using the MiKTeX Options dialog or texhash. If the files are at a root directory gridset the distributor has changed my original distribution archive and you have to copy the files yourself into the appropriate directories at one of your texmf trees and update your File Name DataBase.
If you instead of this have only the files gridset.dtx, README, and gridset.pdf (optional), you have to call:
and follow the instructions.
