To auto-upload all screenshots on Mac, you can open the Preferences menu under Settings in Infinit. Open the Screenshots tab and select the check box for "Automatically upload screenshots."
Each time you take a screenshot with the default Mac keyboard shortcuts for screenshots, Command + Shift + 3 or Command + Shift + 4, the screenshots will automatically upload and copy a link to your clipboard.
Auto-upload selected screenshots
On Mac, you can choose to auto-upload only certain screenshots. What this means is that by using Infinit's specific keyboard shortcuts below, a screenshot will be taken and uploaded in the same step.
A link to that screenshot will automatically be copied to your clipboard as well.
By default, Option + Shift + 3 will take a screenshot of your entire screen.
You can also use Option + Shift + 4 to take a screenshot of a specific part of your screen or Option + Shift + 4, then hit the spacebar to take a screenshot of a single window.
These shortcuts can be modified in the Preferences menu under Settings in Infinit.
