How to make inverse search work in kile+okular

1. In Okular, change the editor from "kate" to "kile". Settings -> Configure Okular -> Editor -> Kile

2. In Kile, first change the build button to "PDFLaTeX", preview button to "View PDF", then add the option "-synctex=1" to the command "pdflatex". Settings -> Configure Kile -> Build -> PDFLaTeX -> add "-synctex=1" in "Options" -> OK

Then in Okular, you can use "Shift+Left Click" to jump to the latex code in Kile.
