10.1. Sun Ray Client Hot Keys

For a Sun Ray Client, there are a number of predefined hot keys that can trigger an activity or event on a client, which are shown in Table 10.1, “Sun Ray Client Hot Keys”. The key sequences can be either a Sun-specific key combination (using keys that might exist only on Sun keyboards) or by an alternative key combination that does not require Sun-specific keys.

The activities controlled by these hot keys are specific to a Sun Ray Client. Desktop software running in the Sun Ray session might provide a separate keyboard shortcut facility that provides additional hot keys for desktop activities, perhaps including the ability to launch certain programs.

By default,the alternative prefix key combinations are Ctrl-Pause and Ctrl-Shift-Alt-Meta. The Ctrl-Pause key sequence is used throughout this documentation. The Ctrl-Shift-Alt-Meta key combination can be changed through the Advanced menu of the Configuration GUI (Enter Alternative STOP modifiers) or the stopkeyskeyword in the .parms file. It can be set to any combination of the four keys, but at least two must be used.


The Meta key has different names on different keyboards: on a PC keyboard, it is the “Windows” key, and on a Mac keyboard, it is the “Command” key.

See Section 10.10, “Configuring the Utility Hot Keys” for details.
