I added a quick launch button for my program editor by entering "D:\EditPlus\editplus.exe" in the Program path field of the quick launch customization panel. Then I found I could drag and drop files onto the button and the editor would open as expected with the dropped file. But I wanted to tell it to open the currently selected file when I clicked on the quick launch button. First I tried putting the string "%1" in the parameter field. Although I don't quite know why, this has worked when I needed to call an external program from dozens of different applications, but it didn't work this time. I also tried putting the string "${sourcefocuspath}" in there, but that didn't work either. The "<" button next to the parameter field seemed to suggest I might need quotation marks around the field, but that didn't help. I suppose I'm doing something pretty obviously wrong, but I can't seem to figure out what.
Thanks
