Accelerator or shortcut for bottons on Chart Sheet

I created a Chart sheet by highlighting data and hitting F11.
I generated some buttons for it by typing this into the Immediate Window
ActiveSheet.Buttons.Add(60, 40, 36, 20.5).Select
and resized and moved them and assigned macros from right clicking.

{Sidebar} That was the only way I could fathom to create the buttons, as the Control toolbox has everything greyed out. I was lucky to find that, because when you type in Immediate Window
?activesheet.
when you type the dot (i.e. what you get when you go Control-J) it doesn't list the available properties or methods. And in the watch window for Activesheet, buttons is nowhere to be seen! At any rate, creating them as I did, I got buttons and macro code set up, and they work perfectly. {/end sidebar}

What I wonder is if I could accelerate (shortcut) the buttons. Ampersand doesn't seem to do anything, and I've found no property to use.

(Bonus question: what is the analogy for checkboxes, not buttons?)
