Active Line Highlight

Active Line Highlight emphasizes the line of text you are currently editing while applying a dark, semi-transparent mask over the rest of the screen, helping you maintain focus.


Behavior & Effects

  • Screen Dimming Mask:
    • Activated by pressing a hotkey (default: F8).
    • Dimms the entire screen except for a horizontal banner area (configured height) centered on your caret position.
  • Ideal for Presentations & Streaming:
    • Perfect for coding demonstrations, live streams, or slides, allowing your audience to track exactly where you are editing.
    • Also acts as a visual accessibility tool for reading or drafting long documents.

Monitor Bounds Detection

  • Automatic Alignment:
    • Detects which monitor the active window is placed on and applies the dimming overlay to the full resolution bounds of that screen.
    • When dragging windows across multiple monitors, the dimming mask automatically snaps and resizes to the correct display.

Customization Options

You can adjust these settings in the “Highlight/Zoom” tab of the settings GUI:

  • Hotkey: The shortcut key used to toggle the active line highlight.
  • Highlight Height (px): The vertical range (10 to 500 px) centered on the caret that remains illuminated.
  • Dimming Opacity (0-255): The opacity of the surrounding dark overlay. Higher values make the background darker.
  • Line Style: Set custom colors and borders for the highlight boundary lines.
