How to Look Up Selected Words in Adobe Acrobat on Mac using Keyboard Shortcuts
Question details
Users want to know if there is a dedicated keyboard shortcut in Adobe Acrobat Pro DC on Mac to directly look up highlighted text in the dictionary instead of navigating through the right-click context menu.
- Product
- Adobe Acrobat Pro DC
- Device & OS
- macOS
- Scenario
- Looking up the definition of a specific word at Dictionary.com or via system dictionary while reading a PDF document.
- Observed behavior
- Adobe Acrobat does not offer a native, customizable keyboard shortcut specifically for the dictionary 'Look Up' command, forcing users to manually click through the Edit menu or context menus.
Ensure you have the text selection tool active and the specific word highlighted in your PDF. On a Mac, you can often bypass application-specific limitations by utilizing system-wide OS shortcuts.
Use macOS System-Wide Dictionary Lookup Shortcuts
Since Acrobat lacks a dedicated shortcut for Dictionary.com, you can utilize the built-in macOS dictionary lookup features to find word definitions instantly.
macOS provides a powerful system-wide dictionary and lookup feature that functions seamlessly across most applications, including PDF readers like Adobe Acrobat. This completely bypasses the need for an Acrobat-specific custom shortcut.
Use your mouse to double-click and highlight the word you want to look up within your PDF document.
Press Command + Control + D on your Mac keyboard. A pop-up will appear displaying the dictionary definition and thesaurus entry for the selected word.
If enabled in your Mac's System Settings, simply perform a three-finger tap on your trackpad while hovering over the highlighted word to instantly bring up the lookup window.

Use Quick Copy and Find as a Search Workaround
If your goal is to quickly locate other instances of the selected word within the same document, utilize standard copy and search shortcuts.
