I saw a Reddit comment mentioning that Ctrl+Shift+PageUp can increase font size, and it works on my dwm setup. However, I couldn't find where this keybinding is defined in my configuration files. Could someone please point me to the correct location?

this is outdated, and likely wont work, a lot of these keybinds are incorrect

Every single one of the above keybinds works in dwm 6.5 (currently the latest version). You might want to check the integrity of your setup.

one can also view all keybindings using man dwm in the terminal
