Hot Keys

When the mouse is in the graphics window, several more commands are accessible via programmable hot keys. They allow you to do things like change mouse modes or advance the animation by a frame by simply pressing a key. The default key bindings are listed in the following tables. The commands listed are the text commands which are executed when the hot key is pressed; these text commands are explained in section §.

VMD keeps a list of user hot keys, which when pressed will result in an associated text command being executed as if it had been typed at the console. There are a number of predefined hot keys, as listed in tables 4.1, 4.2, 4.3, and 4.4. The current state of these can be printed out with the command

The commands attached to these hot keys can be customized by the user.

To add/modify a hot key, use the command

key must be a single character. When that key is pressed while the mouse cursor is in the graphics display window, the associated command will be executed.

Once you have discovered a set of commands which are particularly useful and familiar for you, you will want to have these hot key commands automatically available every time you run VMD. This can be done by placing the commands to add these items in your .vmdrc file, which is a file containing VMD text commands that is executed every time VMD starts up. The basic method for setting up this file is described in section §. Once you have such a file, just put the user add commands in it, and you will have your own specialized version of VMD.
