TeXstudio, SumatraPDF and synctex
Pro tip: if you're using TeXstudio and SumatraPDF - which you probably are, since TeXstudio is the best TeX environment by far, and SumatraPDF is the best PDF reader -, you may be happy to learn that SumatraPDF actually supports synctex files; simply go to Settings > Options, and set the ,,inverse search command line`` to something along the lines of C:\Program Files (x86)\TeXstudio\texstudio.exe "%f" -line %l (the quotes will ensure that this works as intended if your filename contains spaces):
Then simply double-click anywhere in a PDF to go back to the corresponding line of the TeX document - very useful for quickly fixing typos, say.
Conversely, TeXstudio allows you to jump to specific points in the PDF as well using ,,Go to PDF`` in the context menu. In order to make use of this, go to Options > Configure TeXstudio > Commands, and set the External PDF Viewer to something along the lines of "C:/Program Files/SumatraPDF/SumatraPDF.exe" -forward-search "?c:am.tex" @ "?am.pdf":
Side note: the SumatraPDF documentation actually suggests using "C:/Program Files/SumatraPDF/SumatraPDF.exe" -forward-search "?c:am.tex" @ -inverse-search "\"C:/Program Files (x86)/TeXstudio/texstudio.exe\" \"%%f\" -line %%l" "?am.pdf" there to automatically set the relevant SumatraPDF config option, but this does not work for me, so it's better to just set it once by hand.
