The below comes from a derailed Smack Talk thread. I'm re-posting it here in case anyone might find it useful.

Any chance of adding a button or a menu item that would let you edit and save the SWATH.cfg in the next release?

This should is easy to do using zoc:

Code:
Call Zocshell "Notepad.exe C:\Documents and Settings\All Users\Application Data\SWATH\SWATH.cfg", 1
exit


Steps to implement:
1. Copy/paste the above two lines of code to a new text file.
2. Save the file as c:\zocScripts\SwathCFG.zrx - make sure your editor doesn't add '.txt' to the end of the filename.
3. In Swath, configure zoc script directory to c:\zocScripts (Edit->Preferences->Scripts->Page1 or Page2)
4. In Swath, choose menu item Scripts -> Script Tools -> Reload All Scripts.
5. In Swath, hit Alt-X to bring up the trigger list.
6. Add Trigger... select radio 'User button pressed:', then select desired letter from dropdown (the rest of these instructions assume you selected the letter 'A').
7. Select Radio 'Execute script / cmd'; select 'Rexx' from dropdown, select [Scr]SwathCfg.zrx from second dropdown.
8. Hit OK

Hit the 'A' button to edit Swath.cfg using note pad. If you don't have an 'A' button, go to menu View -> Toolbars and make sure 'User' is checked.

Congratulations on implementing your new Swath button!

Note: It might not be necessary to use a zoc script. There is probably an even easier way.

Notepad.exe C:\Documents and Settings\All Users\Application Data\SWATH\SWATH.cfg works pretty good. But it is still outside the program, if you are running multiple copies of swath its a problem because to save the config file, close a copy of swath, it writes the cfg file. Edit the .cfg file and close a second swath, the second swath overwrites your changes to the .cfg file.

So the only way I know of to save an edited swath.cfg, is to edit it with swath completely closed.

Almost.... it should work with just one swath open. But yes, running multiple swath is a problem... you'd have to close all except one, I think.

Actually.... this could probably stand some experimentation. 'Cus I tested it with one swath open, by hitting the 'A' button, editing a macro, then saving notepad. The macro wasn't changed right away in the macro menu, but when I loaded the macro list it was changed.

So I think this probably means Swath reads the cfg file at certain events, probably including opening macro list (alt-z) and loading trigger list (alt-x). So, possibly, with multiple swaths open, after saving the notepad Swath.cfg file you can hit alt-z then ok in each swath instance, and maybe that would load the new config. Then, no problems right? Worth a try anyway.

Even if that works, it would prolly be difficult to automate the multiple swath situation.

Okay I just tried it out, and it seems to work fine - just gotta remember to open trigger list in every swath after saving Swath.cfg.
