I use the following command to lock a keystroke to a function

How do I trap an extended keystroke combination like ctrl-a or alt-c? I know how to check for it but can't see how to use it like above.
Any help is greatly appreciated.

function that_shall_be_run_when_alt_and_c_is_pressed ()
{
...
}

function that_shall_be_run_when_only_c_is_pressed ()
{
...
}
function that_shall_be_run_when_c_is_pressed ()
{
if (key_alt) that_shall_be_run_when_alt_and_c_is_pressed ();
else function that_shall_be_run_when_only_c_is_pressed ();
}

...

on_c = that_shall_be_run_when_c_is_pressed;

Lukas: Thanks for responding! I was confused about how on_alt and on_ctrl works. I would have done it like.
Initialize it.


Then the function.
But this is different than your approach. Will it work?

Hmm, yes, but on_c will also be executed when prssing alt+c. Also, usually you have to hold alt first and then press c for executing the function, yours also allowes first pressing c and then pressing alt.

Thanks for the input! It's Amazing how a little change can really change everything.
