Whether you’re reviewing a lengthy PDF report or browsing through an eBook, this command launches the document in a matter of seconds.

Use Case 2: Navigate Left/Up/Down/Right

Code:

Motivation:

Navigating documents efficiently is crucial when you need to scroll through long pages or inspect detailed blueprints. The vim-like navigation keys in zathura offer intuitive, rapid movement through document regions without reaching for the mouse.

Explanation:

• H|J|K|L: These keys mimic vim’s navigation keys for left (H), down (J), up (K), and right (L) movements, catering to users familiar with modal text editors.
• arrow keys: Alternatively, the traditional arrow keys on your keyboard can be used to navigate the document in corresponding directions.

Example Output:

Pressing these keys causes the document view to shift in the specified direction, ensuring a smooth navigation experience.

Use Case 3: Rotate

Code:

r

Motivation:

Occasionally, documents may be oriented incorrectly, especially scanned images or PDFs. The ability to rotate documents quickly can be essential for legibility and productivity, especially during meetings or presentations.

Explanation:

• r: Pressing the ‘r’ key rotates the currently displayed document page clockwise by 90 degrees, allowing for rapid orientation adjustment.

Example Output:

The document rotates 90 degrees, optimizing it for easier reading or display.

Use Case 4: Invert Colors

Code:

<Ctrl> + R

Motivation:

In low-light conditions, an inverted color scheme can reduce eye strain and improve focus on the content. This feature is highly beneficial for users who often work during nighttime or in dimly lit environments.

Explanation:

• <Ctrl> + R: By holding the Control key and pressing R simultaneously, the document viewer inverts the colors of the content, switching the background to black and text to white.

Example Output:

The colors in the document viewer are inverted, providing an alternative viewing mode that is easier on the eyes.

Use Case 5: Search for Text by a Given String

Code:

/string

Motivation:

Searching for specific text within a document is a common task, whether for research or cross-referencing. The ability to quickly locate passages without manually scanning pages saves time and enhances productivity.

Explanation:

• /: This activates the search mode in the viewer.
• string: Replace ‘string’ with the text you are searching for within the document, enabling the viewer to highlight matches.

Example Output:

Matching instances of the string appear highlighted in the document, streamlining the process of locating relevant sections.

Use Case 6: Create/Delete Bookmarks

Code:

:bmark|bdelete bookmark_name

Motivation:

For lengthy documents, bookmarks function as swift return points, significantly expediting navigation. Users who frequently switch between different sections find bookmarks indispensably efficient.

Explanation:

• :bmark bookmark_name: Typing this command creates a bookmark at the current document location with a specific name you assign, allowing for quick access in future sessions.
• :bdelete bookmark_name: This deletes an existing bookmark, should it no longer be needed or was created mistakenly.

Example Output:

Creating a bookmark generates a quick access point within the document, while deleting it removes that stored location marker.

Use Case 7: List Bookmarks

Code:

:blist

Motivation:

In complex or extensive documents, having an overview of all bookmarks aids in navigation strategy, ensuring users can plan their document traversal effectively.

Explanation:

• :blist: This command lists all the bookmarks currently set in the opened document, providing a clear overview of marked sections.

Example Output:

A list of all bookmarks is displayed, each with its assigned name for easy navigation.
