Configuring Keyboard Shortcuts to Send to the Local System

If you use the Omnissa Horizon Blast or PCoIP display protocol, you can create a view-keycombos-config file to specify which keyboard shortcuts should not be forwarded to the remote desktop.

You might prefer to have some keys or key combinations handled by your local client system when working in a remote desktop. For example, you might want to use a particular key combination to start the screen saver on your client computer. You can create a file located at /etc/omnissa/view-keycombos-config and specify the key combinations and individual keys.

Place each key or key combination on a new line using either of the following formats:

<modName>scanCode

scanCode

The first example is for a key combination. The second example is for a single key. The scanCode value is the keyboard scan code, in hexadecimal.

In this example, modName is one of four modifier keys: ctrl, alt, shift, and super. The Super key is keyboard-specific. For example, the Super key is usually the Windows key on a Microsoft Windows keyboard but is the Command key on a Mac OS X keyboard. You can also use <any> as a wildcard for modName. For example, <any>0x153 specifies all combinations of the Delete key, including the individual Delete key for the US keyboard. The value you use for modName is not case-sensitive.

Specifying the Scan Code for a Key

The scanCode value must be in hexadecimal format. To determine which code to use, open the appropriate language- and keyboard-specific file in the /usr/lib/omnissa/xkeymap directory on your client system. In addition to the key codes listed in that file, you can also use the following codes:

The following list shows the example contents of a /etc/omnissa/horizon-keycombos-config file. Code comments are preceded by the # character.

<ctrl>0x152      #block ctrl-insert
<alt>15          #block alt-tab
<ctrl><alt>0x153 #block ctrl-alt-del
<any>0x137       #block any combinations of the Print key
0x010               #block the individual Q key in a US English keyboard 
                 #or block the individual A key in a French keyboard
0x03b            #block the individual F1 key
0x04f            #block the individual 1 key in a numeric keypad
