I'm using Adobe Acrobat Pro DC 2019 on my mac. I get used to use built-in dictionary of mac via three-fingers clicking on a word. However, it works on other applications like chrome, pdfguru etc. but not on Acrobat Pro DC. Even ^+⌘+D doesn't work. How can I use the dictionary on it?
I come up with a solution by using bettertouchtool but it nearly meets my wish. It opens the dictionary application instead of popping-up.
Download and install Better Touch Tool.
Then select "Keyboard" tab (between "Trackpads" and "Apple remote")
Select "Adobe Reader" at the left sidebar.
Click "Add New Shortcut" and select preferable shortcut (in my case: Command + D).
Then select action: "Controlling Other Application" -> "Send Shortcut to Specific App", select "Adobe Reader" and press "Command + C".
Select newly created shortcut and click "Attach Additional Action" and attach action: "Controlling Other Application" -> "Execute Terminal Command" and paste
