NB 12.13 LESS autocomplete

[Alex Orlov]

Hi all,
 
I wrote to NB user list, but got no answer. Maybe I’ll get help here.
 
I use NB 12.3 and when I edit LESS ( Leaner Style Sheets )  file and press Ctrl 
+ Space
for autocomplete I get "No suggestions" message. Could anyone say if 
autocomplete
is supported and if yes, how to enable it?
