About Screen Marker
For those opening the store 👋 This extension allows you to draw boxes on the screen with only keyboard operations. We have summarized the key points by headings below.
【📋 Quick Reference】
・✏️ Draw Marker: Press and hold the modifier key while dragging → Draws a rectangular marker on the screen.
・🧹 Erase Marker: Clear by tapping the set modifier key within approx. 0.5 seconds.
・🆓 Free Version: 1 settings tab, 1 simultaneous marker, drawing appearance is default style (key customizable).
・⭐ Pro Version: 3 settings tabs, multiple simultaneous drawings, own styles reflected in drawing, export/import settings.
・⚙️ Settings: From the extension icon's popup. Help and language switching are available from the dedicated page.
・⚠️ Note: May not function depending on the website or display method. Treat confidential screens according to internal rules.
【✨ What this extension can do】
・🖥️ Screen Marker is a Chrome extension that allows you to draw rectangular markers on the webpage you are viewing just by dragging the mouse while holding down a modifier key.
・It displays directly overlaid on the browser's display area.
💼 Examples of Uses:
・📸 Temporarily marking areas before taking a screenshot
・💬 Pointing out sections you want to highlight during online meetings or classes
・🎬 Surrounding the area you want others to focus on during an operational demo
💡 Other Points:
・Drawn markers remain on the page and are visible until the page is reloaded.
・There is a minimum size requirement to reduce accidental markings (e.g., very small drags may not draw a rectangle).
・You can manage settings such as color, key, and behavior from the extension icon's pop-up menu.
・Help and upgrade guides can be referenced from pages within the same extension package.
・By default, markers are tied to the display of "that tab." If you switch between multiple tabs, it is recommended to establish a workflow, such as taking a screenshot or note before closing the tab, to ensure everything is captured.
【🖱️ Basic Usage】
✏️ Drawing:
・Drag while holding down all the modifier keys set in the pop-up.
・The default is holding down both the left Shift and left Ctrl keys (can be changed within the product).
🧹 Keys and Clearing:
・You can assign different modifier key combinations for each setting, allowing you to use them according to the task.
・To clear drawn markers in bulk, press and release the set modifier keys within about 0.5 seconds.
⚠️ Caution:
・Depending on your keyboard and OS, some modifier keys, including left/right distinctions, may not be detected as expected.
・We recommend testing in your own environment to ensure there are no conflicts with other shortcuts before adopting them.
🆓 Free Version and ⭐ Pro Version:
・Free Version: Primarily supports markers associated with Setting 1.
・Pro Version: Can handle markers linked to multiple settings.
・If you want to keep markers for a long time, you can adjust the fade-out time and automatic fading behavior in the style settings.
【🎨 Marker Appearance and Style】
🛠️ Examples of adjustable items:
・Fill color・Opacity
・Border color・Opacity・Thickness
・Corner rounding
・Line type (solid, double, wavy, dashed, etc.)
⏱️ Other options:
・Fade out (fades after a certain time)
・Drawing indicator display
・Follow scrolling or not
・Activate only on specific URL patterns
✨ Styling Tips:
・For high visibility: Yellow fill and dark borders.
・For calm explanations: Pastel tones with increased opacity.
・For colorblind friendly or projection environments: Try combinations of high-contrast line colors and moderate fill opacity.
🆓⭐ Difference between Free and Pro Version (Style):
・Free Version: You can change and save styles in the UI, but the default style will be used for actual drawing (note that the preview and actual drawing may not match).
・Pro Version: Saved styles are directly reflected in the drawing.
・Even in the Free Version, you can change key assignments and flexibly set which key combination triggers drawing.
【⚙️ Settings Tab and Key Assignments】
・Pro Version: Three setting tabs (1, 2, and 3). Each can be assigned a different modifier key and style.
・Free Version: Only Setting 1.
🎭 Example of Role Separation (Pro):
・Setting 1: Highlighting important areas
・Setting 2: Thin box for supplementary explanations
・Setting 3: For temporary pointing
📚 Simultaneous Drawing:
・Pro Version: Can keep multiple markers displayed on the screen at once.
・Free Version: Limited to one at a time. New rectangles cannot be added while a marker already exists. This will require clearing between sections or considering Pro.
・For default key assignments, please follow the instructions within the product, and it may be advisable to move one of the assignments to a different modifier key if a conflict occurs.
