Writing and drawing is forbidden on Shabbat - even if it's temporary.
One may not use one's finger to write or draw on the condensation of a window.
One may not write nor draw using water that spilled on a table.
One may not use one's nail to make a mark on page, to enable one to find the place again, or for any other reason.
