Basic usage

• Open PDF viewer: cmd + option + V (the viewer doesn’t open by default, so you need to do this after opening a .tex file). You only need to do this once. The PDF gets refreshed on each build.
• Build: cmd + option + B / cmd + S (auto-build on save)

With the following options LaTeX-Workshop feels similar to TeXShop:

    "latex-workshop.view.pdf.viewer": "tab",
    "latex-workshop.synctex.afterBuild.enabled": true
