This package will add a tab to the GUI page control, providing access to commands for Xy-pic diagrams. Of course, you need to have the Xy-pic LaTEX package installed for this addition to be useful.
Here is a screenshot.
To install the GUI interface for the Xy-Pic diagrams, first backup the winedt.gui file. The winedt.ini file should not change during the installation process, but to be on the safe side, it is probably best to backup that as well. Then unpack the file Xy-pic.zip into a directory %B\temp (%B being the path of the WinEdt directory - so %B\temp would typically be c:\Program Files\WinEdt\temp) that you create for this special occasion. Make sure it contains no other files.
Then start WinEdt and Execute the macro install-xy.edt in %B\temp. You will then be asked for confirmation and should you choose to continue the setup will be done in a few seconds. For the changes to take effect, you need to restart WinEdt. By the end of the installation, you are asked if you want to exit WinEdt.
Finally delete the directory %B\temp.
