- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Annotating or drawing on a PDF document during a presentation or while reviewing in full-screen view.
- Observed behavior
- The user needs a quick keyboard method to activate the Pencil tool without exiting full-screen mode to access the standard toolbar.
Ensure that your PDF document is open in Adobe Acrobat and that single-key accelerators are enabled in your application preferences.
Use Shift+D to Cycle Through Drawing Tools
Since Adobe Acrobat does not provide a dedicated single-key shortcut exclusively for the Pencil tool, you can use the Shift+D combination to cycle through the drawing tools group until the Pencil is activated.
In Adobe Acrobat, commenting and drawing tools are grouped together. By default, the shortcut key 'D' is assigned to the drawing tools category. Using the Shift modifier allows you to toggle through the available tools in that specific group, even when the standard toolbar is hidden in full-screen mode.
Open your PDF in Adobe Acrobat and press Ctrl+L (Windows) or Cmd+L (Mac) to enter full-screen view.
Press Shift+D repeatedly on your keyboard. This cycles through the various commenting and drawing tools available in Acrobat.
Stop pressing the shortcut once your cursor changes to the Pencil tool icon. You can now draw freely on the full-screen PDF.
