Description: PR summary PR checklist [ x] "closes #31093" is in the body of the PR description to link the related issue [x ] new and changed code is tested Plotting related features are demonstrated in an example New Features and API Changes are noted with a directive and release note Documentation complies with general and docstring guidelines Description This PR adds a Ctrl modifier key to 3D mouse rotation so that when Ctrl is held while dragging, the view angles snap to fixed 5° increments (azimuth/elevation/roll). This makes it easier to return to repeatable camera angles when exploring 3D plots. A small test is included to verify snapping behavior when Ctrl is pressed.
