You can change the shortcut keys that display the Run Application dialog in the Keyboard Shortcuts preference tool.
The Run Application dialog is displayed.
If you type only the location of a file, an appropriate application is launched to open it. If you type a web page address, the default web browser opens the page. Prefix the web page address with http://, as in http://www.oracle.com.
To choose a command that you ran previously, click the down arrow button beside the command field, and then choose the command. You can also use the Run With File button to choose a file to append to the command line. For example, you can enter emacs as the command, and then choose a file to edit.
Choose this option for an application or command that does not create a window in which to run.
