A fast, browser-native virtual slide rule.

Drag the slide or cursor with the mouse. Click either one, then use the arrow keys for fine movement, Shift plus an arrow for faster movement, or Alt plus an arrow for a larger jump. You can also enter a number and position either control directly.

About this project: This is an approximation of a traditional logarithmic slide rule, without the calculator from the reference implementation. It is a lightweight, dependency-free browser artifact.
