= class Gtk::CellRendererAccel
Gtk::CellRendererAccel displays a keyboard accelerator (i.e. a key combination like <Control>-a). If the cell renderer is editable, the accelerator can be changed by simply typing the new combination.
The Gtk::CellRendererAccel cell renderer was added in GTK+ 2.10.

+((*------------- FIXME, FIXME, FIXME, FIXME, FIXME, FIXME ---------- (start) ------**))
+:Related to Gtk::CellRendererAccel is not fatal but annoying bug:
+
+ If you wish to display a combined or or'ed together modifier mask which you initially stored in the model the Gtk::CellRendererAccel renderer fails to render the string of modifier keys in front of the modified key. However, it does work for single modifier. You can find the example program on hiki in ((<"Ruby/GTK2 Tutorial"|tut-gtk>)) in section 8.7.5 ((<Keyboard Accelerator Renderers|tut-gtk2-treev-kbda>)). The program name is((*'accelerators.rb'.*)) For your convenience I include here the code segment with the offending code from 'accelerators.rb' program.
