#29: The power of CTRL

#29: The power of CTRL

The familiar computer keyboard has evolved over decades, even though some languages have obstinately different layouts; Germans have QWERTZ and French users have AZERTY, while Brits used to their usual keyboard might struggle to find the backslash on an American machine, and accidentally hit Enter when looking for the hash key.

Most keyboards feature control keys on the bottom corners; designed as a “modifier” to be used in conjunction with other keys to activate certain commands, there are some well-known combos like CTRL+C and CTRL+V for copy and paste. There are outliers – German keyboards have Strg instead of Ctrl, and even an obsolete ISO standard says the key could be marked “?”.

There are some occasions when the Control key is not just a straightforward modifier; aside from using Sticky Keys to keep it pressed, one somewhat hidden feature in the Edge browser turns Ctrl to good effect, for opening an image in a zoomable overlay window.

Many images embedded in web pages are much bigger than you might think; the source picture could be something like 2000x1500 pixels in size, but when displayed on the site, it’s reduced to 640x480. In such cases, you can use the CTRL key to magnify the original image without having to navigate away from the current page.

If the Edge window is in focus, move your mouse cursor over an image and try tapping CTRL twice; if the site can support it, you’ll see the image displayed in a pop-up window that lets you zoom in or out (with the mouse scroll wheel or by stroking your laptop touchpad).

If you have the PowerToys addon pack installed, you may also have Find My Mouse enabled, and that too uses one of the Control keys as its activator. Happily, if a little confusingly perhaps, both can co-exist so you’ll expand the highlighted image while temporarily spotlighting where your pointer is.
