Hover can also be triggered using C-k C-i.
To open a package documentation, hover the package name inside the \usepackage call and click on the View documentation link. As it internally calls texdoc, if it is not in your path you may need to set latex-workshop.texdoc.path to the full path of texdoc and tweak latex-workshop.texdoc.args.
You may also directly run the LaTex Workshop: Show package documentation command from the Command Palette and type in the package name.
When you move the mouse cursor over inline math, \[, $$, \begin{align}, and \begin{...} of other math environments, math preview on hover is rendered. When you move the mouse cursor over \ref, and other reference commands referring math equations, math preview on hover is also rendered.
Supported math environments are align, align*, alignat, alignat*, aligned, alignedat, array, Bmatrix, bmatrix, cases, CD, eqnarray, eqnarray*, equation, equation*, gather, gather*, gathered, matrix, multline, multline*, pmatrix, smallmatrix, split, subarray, Vmatrix, vmatrix.
The tabular environment is not supported.
| Setting key | Description |
|---|---|
latex-workshop.hover.preview.enabled |
Enable math preview |
latex-workshop.hover.preview.scale |
Scale of math preview |
latex-workshop.hover.preview.cursor.enabled |
Render cursor in math preview |
latex-workshop.hover.preview.cursor.symbol |
Define the cursor symbol |

Define the cursor color |
latex-workshop.hover.preview.newcommand.parseTeXFile.enabled |

When latex-workshop.hover.citation.enabled is set to true, moving the mouse over an argument of a \cite related command displays the details of the bibliography as a tooltip.
When latex-workshop.hover.ref.enabled is set to true, moving the mouse over a \ref related command displays the piece of tex with the corresponding label as a tooltip. Moreover, if the label refers to a math environment as described in Preview equations, math preview is rendered instead of showing the tex content. The tooltip has a View on pdf link to jump to the corresponding location in the PDF viewer. It only calls synctex as if you were directly calling SyncTeX from cursor and therefore it requires a PDF viewer for the current .tex file to be opened.
