It would be faster query dictionary with middle mouse button click instead of right click then select "Look Up" menu. Is it possible?

  • Similar question. If you go to OS System Preferences > Shortcuts > Services > Searching > Look up dictionary and add a shortcut, like Cmd + Alt + F, for instance. Then it's a matter of how you want to trigger that shortcut. The answers in that link should give you a few ideas for that. The OP of that question had some ancient mouse with few buttons... so just so know, if you have a more modern mouse, you may be able to use its software to set a specific button to trigger the shortcut you defined for the Look up in dictionary service.

  • The behavior is different but acceptable. It opens dictionary instead of a popup. What's better? The answers in the link reminded me and I found my factory mouse application do have a button setting of Look Up behaviors exactly the same like three fingers tap. Thanks.

  • You know what. On my second glance at this, I found out that the shortcut for the feature you were talking about is Cmd + Ctrl + D, which is different from the service I was talking about. So that would be the one you could've used, had your mouse not had this built in.

    I don't use any of the dictionary features, so this is all kinda new to me. I just felt I needed to mention, because I just realized that the way this cmd + ctrl + d shortcut works is kinda different from what I originally thought. I thought you would have to select a word and then press the shortcut keys, but actually you only have to hover over a word and press the shortcut keys.

You can definitely do it using bettertouchtool, which allows you to reprogram every imput button.
