Post funny things about programming here! (Or just rant about your favourite programming language.)
Blender uses F11 to view render, F12 to render, and F9 to adjust last operation. Shift+F1 through F12 switches through different editors.
And yes of course noone knows that, there's not a single person in the world who knows all Blender shortcuts. More importantly though most F keys are unassigned which means you can bind something to it without unbinding something you never heard about.
