TexStudio forward- and inverse search with build in and Sumtra PDF

I found Alper Yazar's blog helpful. Below is a brief summary:

Step 1. Open configurations - TexStudio >> Options >> Configure TeXstudio... Step 2 Commands >> External PDF Viewer:

"C:Program FilesSumatraPDFSumatraPDF.exe" -reuse-instance %.pdf

Step 3a. Build >> PDF Viewer >> External PDF Viewer

Step 3b. Build >> User Commands >> Add

user0:Forward Search
dde:///"C:/Program Files/SumatraPDF/SumatraPDF.exe":SUMATRA/control/  [ForwardSearch("?am.pdf","?c:am.tex",@,0,0,1)]

Step 4. Shortcuts >> Menus >> Tools >> User: change current shortcut to F2

Step 5. SumatraPDF >> Settings >> Options >> Set inverse search command-line

"C:/Program Files/texstudio/texstudio.exe" "%f" -line %l

Notes: (1) Please adjust paths according to your installation; (2) do not forget quotation marks in step 5; (3) I used SumatraPDF v3.2 64-bit and TeXstudio 3.1.1; (4) in TeXstudio tex-code press F2 to jump to SumatraPDF [forward-search], in SummatraPDF double-click in text to jump to TeXstudio [inverse-search]; (5) if needed: TeXstudio has forward and inverse search, i.e. (a) undo step 3a [use internal viewer] (b) right-click in tex code and select "Go to PDF" (c) in PDF right-click + Go to Source

The following -- rather simple -- setup works for me. In TeXstudio, under Options > Configure TeXstudio > Commands, I set External PDF Viewer to

C:/Program Files/SumatraPDF/SumatraPDF.exe" -forward-search "?c:am.tex" @ "?am.pdf"

and in SumatraPDF, under Settings > Options, I set Set inverse search command-line to

C:Program Files (x86)TeXstudiotexstudio.exe "%f" -line %l

This works even for filenames containing dashes, underscores, spaces, umlauts and other such things. You may need to adjust those paths, of course.
