Inline Editing

WinXMerge supports WinMerge-style inline editing — you can edit text directly in the diff panes.

Editing is always in aligned Ghost-line view (no separate edit mode). Changes are reflected immediately in the diff display.

ActionKey
Insert new lineEnter
Delete empty lineBackspace (at start of line)
Move between rowsArrow Up / Down
Rescan diffF5
UndoCmd+Z
RedoCmd+Shift+Z

When you insert a new line in one pane, a ghost line is automatically added to the other pane to maintain alignment.

Press F5 to recompute the diff from the current edited content. This is useful after making multiple edits to see the updated diff state.

Create empty comparison documents for editing from scratch:

  • File → New → Text: Empty 2-way comparison
  • File → New → Table: Empty CSV/TSV comparison (10x5 grid)
  • File → New (3-pane) → Text / Table: Empty 3-way comparison
