Well a text file. Whether you use Notepad, word pad, Notepad++, etc. It's a file you name toolBox.txt or whatever you like and you put all you code in there. Such as all your page setup code for index pages, href links, divs, etc. Instead of typing it out you can just copy paste it and it makes writing out the pages faster and safer considering you aren't typing so you have a less chance for error; typos.
Here is the start of my toolbox. Mind you I am only a student so it's not very well developed yet but my professor has strings and strings of coding he can call on.
Edit: I always put the last time I updated it at the very top. Month.YearCode
