A computer-implemented method, comprising: generating a screen capture user interface for display on a display of a computing device, including: generating a first section of the screen capture user interface providing for selection of a first capture mode or a second capture mode, and generating a second section of the screen capture user interface providing for selection of a screen capture area; displaying the screen capture user interface on the display of the computing device, such that the screen capture user interface floats on the display; detecting selection of a screen capture mode on the screen capture user interface; and operating in the selected capture mode in response to detecting the selection of the screen capture mode, including: triggering operation in the first capture mode in response to detection of selection of the first capture mode, the first capture mode being a screenshot mode for capture of still image content output by the display of the computing device; and triggering operation in the second capture mode in response to detection of selection of the second capture mode, the second capture mode being a screen recording mode for capture of moving image content output by the display, wherein operating in the selected screen capture mode in response to detecting the selection of the screen capture mode further includes: operating in the second capture mode and capturing a screen recording of the moving image content output in a screen recording capture area of the display in response to detection of the selection of the second capture mode, detecting a selection of the first capture mode on the screen capture user interface while operating in the second capture mode, and triggering operation in the first capture mode and capturing a screenshot while capturing the screen recording. generating a screen capture user interface for display on a display of a computing device, including: generating a first section of the screen capture user interface providing for selection of a first capture mode or a second capture mode, and generating a second section of the screen capture user interface providing for selection of a screen capture area; generating a first section of the screen capture user interface providing for selection of a first capture mode or a second capture mode, and generating a second section of the screen capture user interface providing for selection of a screen capture area; displaying the screen capture user interface on the display of the computing device, such that the screen capture user interface floats on the display; detecting selection of a screen capture mode on the screen capture user interface; and operating in the selected capture mode in response to detecting the selection of the screen capture mode, including: triggering operation in the first capture mode in response to detection of selection of the first capture mode, the first capture mode being a screenshot mode for capture of still image content output by the display of the computing device; and triggering operation in the second capture mode in response to detection of selection of the second capture mode, the second capture mode being a screen recording mode for capture of moving image content output by the display, triggering operation in the first capture mode in response to detection of selection of the first capture mode, the first capture mode being a screenshot mode for capture of still image content output by the display of the computing device; and triggering operation in the second capture mode in response to detection of selection of the second capture mode, the second capture mode being a screen recording mode for capture of moving image content output by the display, wherein operating in the selected screen capture mode in response to detecting the selection of the screen capture mode further includes: operating in the second capture mode and capturing a screen recording of the moving image content output in a screen recording capture area of the display in response to detection of the selection of the second capture mode, detecting a selection of the first capture mode on the screen capture user interface while operating in the second capture mode, and triggering operation in the first capture mode and capturing a screenshot while capturing the screen recording. operating in the second capture mode and capturing a screen recording of the moving image content output in a screen recording capture area of the display in response to detection of the selection of the second capture mode, detecting a selection of the first capture mode on the screen capture user interface while operating in the second capture mode, and triggering operation in the first capture mode and capturing a screenshot while capturing the screen recording.
