* Closes https://github.com/emilk/egui/issues/7120 You can now zoom only the X axis by holding down shift, and zoom only the Y axis by holding down ALT. In summary * `Shift`: horizontal * `Alt`: vertical * `Ctrl`: zoom (`Cmd` on Mac) Thus follows: * `scroll`: pan both axis (at least for trackpads and mice with two-axis scroll) * `Shift + scroll`: pan only horizontal axis * `Alt + scroll`: pan only vertical axis * `Ctrl + scroll`: zoom all axes * `Ctrl + Shift + scroll`: zoom only horizontal axis * `Ctrl + Alt + scroll`: zoom only vertical axis This is provided the application uses `zoom_delta_2d` for its zooming needs. The modifiers are exposed in `InputOptions`, but it is strongly recommended that you do not change them. ## Testing Unfortunately we have no nice way of testing this in egui. But I've tested it in `egui_plot`.
