A window appears for each file you specified, as well as an extra window for the results of the merge. To identify which file is in a window, look at the title bar at the top of the window.
The Editor pauses at each point where the two files are different, and highlights the text that differs. Using the Control Panel, you can select which one of the highlighted sections, or both, to copy into the results window. You can also manually cut and paste text into the results window. Listed below are the features of the results window:
The Editor finds the next difference.
Invokes help on the control panel.
Aborts the merge, closing all merger windows.
Copies the selected text from File1.
Copies the selected text from File2.
The first time you press this button, a dialog box appears asking you how you want to merge the two selections: in what order, with change bars around them, with comments in front, between, or after them, and so forth. The next time you press this button, the last values entered are used.
Changes the way the Both button works, and invokes the same dialog box as the first time you press the Both button.
When merging is complete, the windows on the original files are removed and a dialog box allows you to save the results window. If you save it as the same name as one of the original files, then any windows still looking at that file are replaced with the merged results. After saving, the results window is removed.
