# Window preferences

The Window preferences allow you to set the default window appearance such as widow size or line number display.
Changes you make here will take effect when you next create/open a document.

□ Show navigation bar
  With this option turned on, CotEditor's navigation bar appears beneath the toolbar.

□ Show line numbers
  With this option turned on, CotEditor shows line numbers on the left side of the window.
  □ Show wrapped-line mark
    With this option turned on, you'll see a mark indicating that the line next to it is being wrapped. When this option is off, nothing is displayed.

□ Show status bar
  With this option turned on, CotEditor shows a status bar at the bottom of the window.
  □ Show thousands separator
    With this option selected, numbers are displayed with thousands separators.

□ Show page guide
  When this is turned on, a page guide (a vertical gray line) is displayed in the window's text view area.
  Display at column:
    You can specify the column at which you want the page guide displayed. Note that the display position will differ according to your font setting.
    The default font type can be changed in the Format preferences.

Window Size
  You can set the default window size. Clicking “Get from sample window” opens a sample window so that you can set the width and height visually.

Window Transparency
  You can set the default window tranparency using the slider.
  □ Text view only
    When this option is selected, the transparency setting affects only the text view area. Otherwise, it affects the whole window including such as the title bar and the scroll bar.
