The controls on this settings page are used to configure the behaviour and appearance of text comparison windows.
Show line numbers and byte offsets
When this setting is checked, Merge will display line numbers or byte offsets at the left of each file panel.
Indicate where changes are concealed at line ends
Check this setting to have Merge display an indicator at the end of each line that contains changes located off the right-hand edge of the visible portion of the line.
Show CR and LF characters
When this setting is checked, Merge will show the trailing Carriage Return and/or Line Feed characters at the end of each line. This is purely a visual setting, and does not affect the line endings used when files are saved (you can choose those in the Save dialog).
Show whitespace characters
When this setting is checked, Merge will show visible glyphs in place of space and tab characters.
Wrap long lines
Check this setting to have Merge use multiple lines on the screen to display a long line of text.
Break lines at word boundaries
Check this setting to wrap text at word boundaries instead of at the character nearest the edge.
Show context around changes of only # lines
Check this setting to collapse sections of unchanged lines. The adjacent entry field can be used to specify how many lines should be shown at the top and bottom of the collapsed section to provide some context for the collapsed lines.
