< 3.5 GHz, 6-Core Mac Pro (2013 MacPro6,1) with 16GB RAM and D700 GPUs, running macOS 10.14.6 >
After reinstalling MacOS 10.14.6, whenever I type cmd-control-d, a window pops up with dictionary entries.
I have never seen this before (since 1986!) and have been unable to find where the command is controlled so that I can stop the pop-up window from appearing. I need this to stop, as I have used cmd-control-d for decades to generate a time-and-date stamp.
Any advice would be appreciated!
