File inclusion navigation
Next to commands that include other files, there is a gutter icon.
You can click on it to bring you to the file, or you can use Ctrl+B when your cursor is on the filename.
This includes commands like \documentclass, \usepackage and \includegraphics and many more.
TeXiFy supports the import package with which you can include other LaTeX files.
Its main feature is the ability to set import path prefixes when you included a file.
For example, if you have main.tex which contains \subimport{chapters/}{chapter-one.tex}, and two files chapters/chapter-one.tex and chapters/included.tex, then in chapter-one.tex you can do \input{included.tex} and it will resolve correctly.
Without the import package, you would need to write \input{chapters/included.tex} for the include to work.
The package also has the \import command for absolute instead of relative paths.
For more information, see http://mirrors.ctan.org/macros/latex/contrib/import/import.pdf
When you have a file or bibsource field, the content can include a path (absolute or relative) to a local pdf file from which the bibtex entry was created.
Then when you press Ctrl+B when your cursor is on the file path, the file will be opened.
An example:
@book{knuth1990,
author = {Knuth, Donald E.},
title = {The {\TeX} book },
year = {1990},
isbn = {0-201-13447-0},
publisher = {Addison\,\textendash\,Wesley},
bibsource = {../literature/knuth1990.pdf},
}On Linux, the Mendeley format is also supported, which is of the form
file = {:home/user/.local/share/data/Mendeley Ltd./Mendeley Desktop/Downloaded/filename.pdf:pdf;:home/user/.local/share/data/Mendeley Ltd./Mendeley Desktop/Downloaded/filename2.pdf:pdf}
