When I create a screenshot of a part of my screen by pressing Shift-Command-4 and then selecting the area using the trackpad, often I release the trackpad in the wrong time, which means the screenshot doesn’t look good.
To “fix” this issue in my life, I would prefer to have a keyboard shortcut, which, if I press it quickly enough — before the file would appear on a Desktop, will cancel its creation. Does such a thing exist, or maybe something similar?
It’s like you released the trackpad in the wrong time, said “oops”, quickly pressed the Escape key, and by this, prevented that screenshot to appear.
You can right-click on the thumbnail that appears for a while and click Delete. I don’t think there’s anything quicker. (Dismissing the thumbnail by dragging it to the right will save the screenshot to the desktop, which is not what you want.)
Tip of the day: Although I’m sure most here know this, when using Shift-Cmd-4, you can press Space before clicking to capture the entire window, eliminating the need to select a part of the screen if this is what you are trying to do. You can also additionally press Option before clicking to capture a screenshot without a shadow.
I often just use Shift-Cmd-5 instead for this very reason. This variation of the screenshot tool allows to preview and resize the area and an explicit capture or return is required to actually take the screenshot.
If you have Dropbox installed on your Desktop, they have a function to auto-magically move Screenshots to a Dropbox folder of the same name. Then the Screenshots are all in one place and you can monitor/ delete them manually or run a Hazel (or other) script to purge on regular intervals.
