Make reading comfortable
Open Reading Appearance (Aa) to adjust the current window. Choose GlyphGlance → Settings… → Reading to save defaults for your document windows. Use Saved Preferences removes a window's temporary adjustments.
Choose a font, text size, line spacing, margins, paragraph indent, and alignment. Fit Window uses the available width; Readable Column keeps long lines within a preferred width. Wide code blocks and tables can scroll sideways.
Appearance chooses System, Light, or Dark for the reading window. Theme chooses Default, Sepia, Gray, or your own Custom page colors. System follows macOS; these choices do not change other apps. Custom offers separate light and dark background colors.
Use the toolbar's Zoom menu or Command–Plus / Command–Minus to magnify the document. Actual Size (Command–0) resets magnification. Zoom to Fit (Command–9) follows window resizing; Fit Window text already uses the available width.
Reading preferences do not change the source file, Finder Quick Look, or exported documents. Restore Default Reading Preferences in Settings restores the built-in reading settings.
Continuous or paged reading
Choose View → Reading Layout → Continuous to scroll, or Paged to turn pages. The same choice appears in Reading Appearance and Settings. In Paged layout, choose One Page or Two Pages.
Turn pages with the buttons below the document, Left/Right Arrow, Page Up/Page Down, a horizontal trackpad swipe, or a click in the blank left or right page margin. Keyboard page commands work when the document has focus. Links, text selection, search, and sideways scrolling inside wide tables keep their usual behavior.
Pages adapt to your window and reading preferences. If a layout cannot be divided safely, GlyphGlance returns to continuous reading. Animate Page Transitions controls page-turn animation; macOS Reduce Motion also disables it.
Reading Mode
Choose View → Enter Reading Mode or press Shift–Command–R for a quieter window. The main toolbar and Info sidebar disappear; Contents, Reading Appearance, and Overview remain available at the top.
Choose Exit Reading Mode, press Shift–Command–R, or press Escape to restore the previous toolbar, Info sidebar, and zoom. Escape closes an open Contents or appearance popover or Find bar first.
To enter full screen automatically, enable Settings → Reading → Reading Mode → Enter full screen when using Reading Mode. It is off by default. Leaving Reading Mode restores the previous window size; a window that was already full screen stays full screen. You can also use the green window button or Control–Command–F independently.
