Being able to easily find documentation is critical when programming. Cursive tries to show you all the doc you need everywhere you might need it.
When using a function, it's often very useful to know the parameters it accepts. You can get a summary of them with Ctrl+P (). This popup will persist until you press Esc or the caret leaves the form.

You can also get the full documentation for the symbol under the cursor using Ctrl+Q ().

If you really need to know what's going on, you can even get the source code of the function using Ctrl+Shift+I ().

These popups are available in many places in the editor, for example in the autocompletion list:

And in the navigation bar:

ClojureDocs is a community-driven repository of additional information about core Clojure functions. Cursive allows you to download an archive of all the ClojureDocs information, and then it will enhance the built-in documentation using that information.
When you first start Cursive, you'll be prompted via a notification. Click the Download link, and Cursive will download the archive for you.

Then, when viewing documentation using Ctrl+Q () as above, Cursive will enhance the view, showing you examples, notes and see-also information with hyperlinks to related functions.
