Default button bindings

The button bindings that are provided with your system are referred to as default button bindings. Most default button bindings can be reconfigured.

All bindings are located in the /usr/lib/X11/system.pmwmrc file (for pmwm mode) or the /usr/lib/X11/system.mwmrc file (for mwm mode) in the Buttons section type. The default bindings are defined by a set named ``DefaultButtonBindings.'' System administrators can customize the functionality of some button bindings and make system-wide changes by editing this file. Users can customize the functionality of button bindings in their local environment by copying the appropriate system-wide window manager configuration file to either .pmwmrc (for pmwm mode) or .mwmrc (for mwm mode) in their $HOME directory.

The entries in the ``DefaultButtonBindings'' section of the system-wide window manager configuration file look similar to these:

   Buttons  DefaultButtonBindings
   {
           .         .             .
      <Btn1Down>   frame|icon   f.raise
      <Btn2Down>   frame|icon   f.post_wmenu
           .         .             .
           .         .             .
   	
   }

Each line in the ``DefaultButtonBindings'' section represents a button binding. A button binding consists of a button action (such as Btn1Down), the window manager context in which the action is valid (such as frame), and the function the action provides (such as f.raise). Button actions, contexts, and functions are discussed in more detail later in this chapter.

``Default button bindings'' lists the default button bindings.[1]

You can reconfigure the default button bindings or create new button bindings and add them to the default binding set. In addition, if you want to underscore to yourself that you are using your own bindings rather than the default bindings, you can create your own sets of button bindings.
