[Geany] code completion on fc6

[nn101]

Hello,

I am using Geany (0.10) on Fedora Core 6 to edit (wx)python scripts but 
don't know how to get the 'code completion' component to show.

I imagine 'code completion' activates a small pop-up scrollable list 
that appears near the cursor after a few letters have been typed, and 
lists syntax that may be appropriate for the word that has been entered. 
Unfortunately I don't know how to activate this feature on my system.

Can someone tell me how to show a code completion window when editing 
(wx)python scripts ?

Many thanks.

Nick
