macosscreen capture
I am attempting to take a screenshot of a tooltip that appears when a user hovers over it, and immediately disappears upon any key press or cursor movement. Unfortunately, this means the typical shortcut I use for screenshots (⌘+SHIFT+4) causes the element to disappear.
Is there any way I can capture this tooltip, preferably without installing any third party software?
OS X has a command-line tool called screencapture that makes a screenshot. Try this:
screencapture -T 5 -t tiff ~/Desktop/screenshot.png (the "-T 5" option specifies a 5-second delay; the "-t tiff" option specifies saving the data in the uncompressed tiff image format)With a full-screen screenshot, you can use the crop tool in Preview.app to save the region of the screen that you want.
You can set up a custom shortcut, for example a key, for that purpose.
Open System Prefrences, go to Keyboard -> Screen Shots (or navigate to the Screen Shot-options), and double click on the shortcuts you want to change to change them to the keys you use less frequently. If you have a huge keyboard like me, you can for example set the F5 and F6 to be the shortcuts.
Here is a screen shot of the settings window where you set the shortcut (captured with those as well!) The "Copy"-screenshots are the ones with Control+Shift.

You can do this using the screencapture CLI:
Define a delay using
-T <seconds>. Use-Cto capture the cursor too.Add
-ito capture interactively. This uses the normal capture region selection available from ⌘⇧4, however you can combine this with-Tto add a delay so that it captures the tooltip in the region.
