- Device & OS
- not provided
- Scenario
- Reading and annotating a PDF document in full-screen or presentation mode without wanting to exit the view to access tools.
- Observed behavior
- Highlighting tools and toolbars are currently hidden or inaccessible during full-screen mode, disrupting the reading and annotation workflow.
Check your current PDF software version to ensure you have the latest reading and annotation features installed, as touch gestures and full-screen layouts vary between updates.
Utilize Keyboard Shortcuts for Highlighting
Use built-in keyboard shortcuts to activate the highlight tool without needing a visible toolbar.
While in full-screen or reading mode, most major PDF applications hide the main toolbar to maximize your viewing area. However, the core tools remain active via keyboard shortcuts.
Open your document and press 'Ctrl + L' (Windows) or 'Cmd + L' (Mac) to enter full-screen mode.
Press the standard shortcut key for the Highlight tool (often 'U', 'H', or 'Shift + U' depending on your software) to select it.
Click and drag over the text you wish to highlight. Press 'Esc' when you are done to return to standard navigation.

Frequently Asked Questions
Why does the toolbar disappear in full-screen PDF mode?
Full-screen mode is specifically designed for presentations and distraction-free reading. To maximize screen real estate, editing toolbars and menus are automatically collapsed or hidden.
Can I customize touch gestures in my PDF reader?
Touch gesture customization is generally limited and depends heavily on the specific software and operating system. While basic pinch-to-zoom and swipe-to-scroll are universally supported, custom multi-finger swipes for toolbars usually require developer implementation.
How do I exit full-screen mode to get my highlighters back?
In almost all PDF readers, you can instantly exit full-screen mode by pressing the 'Esc' (Escape) key on your keyboard, which will return you to the standard view with all toolbars visible.
Is there a way to pin the toolbar while reading?
Many PDF applications offer a 'Read Mode' (different from Full Screen) that removes side panels but keeps a streamlined, pinnable floating toolbar at the top or bottom of the screen for quick annotations.
