5.5.2.3 Keyboard One Shot Modes
•In the Keyboard Properties dialog box, open the One Shots tab.
Figure 5.9 Keyboard One Shot Properties
When these options are enabled, the <ORANGE> and <BLUE> keys only remain 
active until the next key is pressed. If the ‘One Shots’ options are disabled (the checkbox 
is left blank), the <ORANGE> and <BLUE> keys are locked ‘on’ when pressed only 
once; they remain ‘on’ until they are pressed a second time to unlock them.
Note: Keep in mind that checking the taskbar lets you know whether or not 
these keys are locked ‘on’. When the <ORANGE> and <BLUE> keys 
are locked ‘on’, the taskbar at the bottom of the screen displays them 
in uppercase characters – 
BLUE KEY and ORANGE KEY. If these keys are dis-
played in lowercase characters in the taskbar, you’ll know that the 
Blue Key 
and the 
Orange Key are not locked. They will become inactive following a 
key press.
