guys,

there are 80 keybord buttons i have: 77 'working' buttons and 3 'assignable' buttons - ctrl, shift and alt. how many shortcuts i can arrange with this keybord?

shortcuts mean you use assignable buttons in either combination: either single ctrl with other 77 buttons or ctrl + alt with those 77 etc.

ps. i've got 82,160...

Here is what I get

With one assignable button = 3 * 77 = 231
With 2 assignable buttons = 3C2 *77 = 231
With 3 assignable buttons = 77

Total number of combinations = 539.

Assuming ALT + 77 keys also makes valid combination
Also CTRL + ALT + anykey is same as ALT+CTRL+any key
then we have

(3C1 + 3C2 + 3C3 ) * 77 = 539 combinations
