Crosshair

Crosshair adds a fullscreen overlay cursor – a horizontal line and a vertical line that follow your mouse. Use it for alignment, layout, measuring, design, or on-screen aiming. Toggle it with Option / Alt (or your own shortcut). Click or press Esc to turn it off. Features • Fullscreen crosshair that tracks the cursor • Freeze marks: drop a crosshair in place and keep moving the live one, as many times as you need • Pause the extension from the popup so it does not intercept your shortcuts • Adjustable line thickness (0.25 – 10 px) • Custom color • Optional “dismiss on click” • Custom keyboard shortcuts (bound to the physical key, works with any keyboard layout) • Light, dark, or system theme • Many interface languages • Works over nested pages and iframes • Settings stay on your device How to use 1. Click the Crosshair icon in the toolbar, or press Option / Alt. 2. Move the mouse – the lines follow. 3. Click or press Esc to hide the overlay. 4. Open the popup to change thickness, color, shortcuts, theme, or language. 5. Optional: assign a Freeze key, then press it to leave a mark at the current position. Clear the Freeze key with the trash button next to it. What’s new in 1.1.1 • Freeze shortcut with unlimited marks • On/Off button in the popup • Crosshair works inside iframes (for example Tableau, Power BI, Google Sheets, Looker Studio, Figma, etc.)
