To change these settings in the CotEditor app on your Mac, choose CotEditor > Settings, then click Window.

OptionDescription
Open documents in tabs Choose when documents are opened in tabs instead of new windows:
  • Respect System Setting: Respect your setting for the ”Prefer tabs when opening documents” option in the Windows section in the Desktop & Dock pane in System Settings.
  • Always: Always in tabs as long as more than one document is already opened.
  • Automatically: Only when you’re working in full screen, or multiple documents are opened at once.
  • Manually: Only when explicitly open in tabs.
Window size Set the default window width and height in pixel. If the fields are left blank, the size of the last window is adopted.
Line numbers Show line numbers on the leading of the editor.
Invisible characters Draw invisible characters — such as line endings, whitespaces, or control characters — as alternative symbols to make them visible. See Display invisible characters for about the available types of invisible characters.
Indent guides Draw guides for each indent width in the indent parts of the editor.
Page guide Show a page guide line at a specific column in the text editor area. Note that the drawing position differs according to the text font. The default font can be changed in the Appearance pane.
Change background color Highlight the lines in which insertion points exist with another background color. The Current Line color in the selected theme is used for this highlight.
Wrap lines to editor width Soft-wrap long lines at the window edge so that they are visible. Otherwise, a horizontal scroll bar is shown instead of wrapping text.
Indent wrapped lines Visually indent Hanging lines automatically. Additional indent width can also be set.
Writing direction Choose the default writing direction in editors.
Overscroll Choose the amount of the extra space at the bottom of the editor to scroll past the end of a document. By 0%, the scroll stops after reaching the end of the document; and by 100%, the scroll continues until only the last line is visible.
Status bar shows Choose the information to appear in the status bar at the bottom of the window.
