DEVTOOLS ZOOM

Guide on zooming in browser developer tools using keyboards where the + key requires the Shift modifier, but the shortcut does not work as expected.

Gecko

• Navigate to about:config
• Search for devtools.toolbox.zoomValue
• Edit the zoom value
• The setting will take effect in a new tab

Blink

• Navigate to chrome://settings/
• Search for zoom
• In French the setting is called Zoom de la page
• If you’re using a French version, you can directly navigate to this link: chrome://settings/?search=Zoom+de+la+page
• Change the zoom level. It will affect both the dev tools and the page. It is also the new default value for the default zoom Cmd 0
• Adapt the zoom of the page with Cmd Shift + or Cmd Shift -
• NB: Behaviour is slightly different in Chrome, Opera and Brave

WebKit

• The shortcut Cmd Shift + works, so no hacks are needed.
