Fw: [vox-tech] Using setleds

[John Wojnaroski]

Okay, got that working just fine. Is there an argument for 
XTestFakeKeyEvent that would just change the LED and  not the state of 
the flags; analagous to "setleds -L +caps"

Trying 'system( "setleds -L +caps" );' returns the standard complaint  
... stdin is not a VT

Regards
John W.
