Start editing a GtkCellRendererText using F2

[Andrew Smith <asmith15 littlesvr ca>]

Hi

I have a GtkTreeView and one of the columns is an editable 
GtkCellRendererText.

I would like to have the F2 key edit the cell, just as clicking on it 
does, but I can't figure out how.

I can do 
gtk_accelerator_parse()/g_cclosure_new()/gtk_accel_group_connect() to 
have a callback called when F2 is pressed but I've no idea how to tell 
the callback to edit the selected cell.

Is this doable?

Thanks in advance,

Andrew
