Keyboard shortcuts

Nothing here is required — every action has a visible control too — but a converter you use daily is faster without the mouse. Single-letter shortcuts never fire while you are typing in a field.

Anywhere on the site

Keys	Does
`Ctrl` + `K`	Open the search palette. ⌘ K on a Mac.
`/`	Open the search palette, unless you are typing in a field.
`Shift` + `D`	Cycle the theme: system → light → dark.
`,`	Open settings.
`?`	Open this page.
`Esc`	Close the palette, a dialog or the mobile menu.
`Tab`	Move forward through every control; Shift + Tab goes back.

In the search palette

Type a conversion — 12 kg to lb — and the answer appears as the first result, computed in the palette itself.

Keys	Does
`↑`	Previous result.
`↓`	Next result.
`Page Up`	Back five results.
`Page Down`	Forward five results.
`Home`	First result.
`End`	Last result.
`Enter`	Open the highlighted result, or the first one if none is highlighted.

On a converter

Keys	Does
`S`	Swap the two units.
`C`	Copy the answer.
`Enter`	Recompute — useful after pasting.
`↑` + `↓`	While a value box is focused, the stepper buttons beside it nudge the value.

On a calculator

Keys	Does
`Alt` + `↓`	Next input field, skipping the unit pickers.
`Alt` + `↑`	Previous input field.
`C`	Copy the headline answer.

Accessibility

Every control on the site is reachable by keyboard and shows a visible focus ring. The result region of a converter and of a calculator is a live region, so a screen reader announces a new answer without the focus moving. Copy confirmations and theme changes are announced politely, so they never interrupt.

Text size, high contrast and the graph-paper background are all in , and every animation on the site is disabled when your system asks for reduced motion.
