^"Source" means you see and edit the TeX source files. "WYSIWYM" = What You See Is What You Mean, i.e. you see and edit formatted text. WYSIWYG means that see the output file automatically updated during the edit. Note that some PDF viewers (e.g. evince) automatically reload the PDF document when it is updated on the disk. So, any "source" TeX editor can be turned into partial WYSIWYG editor by opening such a reader in an adjacent window.
^Not a full TeX editor. Only limited to math expressions only.
^Support for non-linux systems considered experimental.
^TeXmacs is an original document preparation system, with own syntax and own algorithms, but can be used to obtain TeX files through its LaTeX export capability.
^Requires installation of LaTeX Workshop
extension.
^Inverse search means that one can locate the relevant part of the source code from the viewer (e.g., double-clicking in dvi or pdf file brings up the appropriate line/paragraph in the latex code)
^On Windows some pdf viewers like Sumatra PDF or Adobe Reader don't use command line arguments for forward search, but the editor sends the document position to them using Dynamic Data Exchange
^With usual \section{} notation, Kile collapses equations and figures, but not sections. Collapsing of sections is possible with non-standard notation \begin{section}{}...\end{section}{}, but it eliminates sections from Structure View. An alternative possibility is bracketing sections with comments %BEGIN and %END.
