For example there is in Mavericks under System Preferences, Keyboard, Shortcut, Services: "Open selected file in TextEdit". The problem is that I want to use a different editor, not only for a one type of file, but for any selected files, just like this example says, selected file. I want to usually open configuration files, or files without extension and its too complicated to assign always open with for each file extension. Programmers can help. Edit I found out that I have to edit the .plist in the package of the app, and I copied and changed the name of TextEdit with the app I want to use in the following code. The problem is that the default shortcut does not even work for TextEdit. I don't understand what the problem is. I think some other people observed this bug before ?
