a book in Japanese and I have noticed that there are comma-like symbols next to some words, but I have no idea what they are for. In the photo attached, they are to right of とりあえず.
JFYI, a native speaker told me that these marks (which are called 傍点 [ぼうてん]) are also used when lots of kana are used in a row, to indicate where a certain word begins and ends.
