The revised Screenshot utility in Mojave brings the handy option of choosing if the resulting Screenshot should be copied to the clipboard or saved as a file, or saved to email, etc.
However this requires that I first press Cmd+Shift+5 to bring up the options, then select my desired option using the pointer. I find myself often needing to switch between saving to a file and saving to the clipboard and wondering if there is a way to do this by a keyboard command or modifier.
For example it would be great if I could use Cmd+Shift+4 to capture a selection, but modify the command to save-to-clipboard or save-to-file.
Grateful for any suggestions.
