If you have several environments that you develop and test in, you may find it useful to create bookmarklets for frequently-accessed pages.
For example, let's say I have four environments: local, development, integration and testing. For each, I may want to easily get to one of six pages with a complex path, without having to navigate to that path. I could create six bookmarks for each environment, but who wants to create 24 bookmarks?
I can create a single bookmarklet, and use it to get to the corresponding path on the site I'm signed into. Here's the syntax (replace /path with the specific path you're bookmarking):
Once you have the bookmarklet in your browser, sign into the environment you're testing in, and then click the bookmarklet to jump to that path.
