Marcin Wichary 推荐一个长期被忽视的 MacOS 内置功能：在辅助功能设置中开启‘使用修饰键滚动缩放’后，按住 Control 并用双指滑动即可即时缩放整个屏幕。关闭‘平滑图像’选项还能获得像素级清晰显示，这是无需第三方软件的强大生产力工具。

Go to Settings > Accessibility > Zoom, and then turn on “Use scroll gesture with modifier keys to zoom.”

Then, at any moment, you can hold Control and swipe with two fingers (or use a scroll wheel) up or down to zoom the entire screen.

I’d also recommend turning off “Smooth images” under “Advanced…” so you see individual pixels better:

Over the years, I found this feature very useful to inspect various misalignments, to check visual details, and occasionally simply to read text that’s too small.

Compared to other ways of zooming, this one has three benefits:

it’s extremely motor-memory friendly and so my fingers do it without me even thinking

it’s a system-wide thing, so it will work everywhere

it’s safe, because it’s something that I call a peek gesture

Peek gestures are fast, but the main benefit is that they’re safe. In some apps, pressing ⌘+ a few times and then ⌘– the matching amount of times doesn’t guarantee you will end up back in the same situation. The window size might change, the scroll position might move, the cursor might end up in a different place. In contrast, the Ctrl gesture is 100% deterministic and reversible; it will always work the same and never mess anything up.

I treasure peek gestures in general. Here are a few other useful (and/or inspiring?) ones:

previewing things in Finder by pressing (or, for power users, holding) the spacebar

using ⌘⇧4 with the intention not to take a screenshot, but just to (roughly) measure a distance between two objects, and then pressing Esc to abort

in tools like Figma and Sketch, using Ctrl+C just to quickly verify the color, and pressing Esc to cancel (rather than clicking to put the color into the clipboard or apply it elsewhere)

I also previously mentioned Chrome typeahead and macOS menus that had a similar property
