All your ideas are not possible to realize (at least I see now way for
it currently). The only thing I can imagine is the following: Add to
your
source a dummy function

void breakpoint()
{
}

and then set a breakpoint to this function (NOT using the Ctrl+F8 key
but using the breakpoints dialog, where you can set a breakpoint to
a function!!!). Then you can use the above code:

if (key[KEY_SPACE]) breakpoint();

which will work also, when you have deleted/inserted some source lines,
because the breakpoint is set to the function independet of its source
line.

(be not irritated when the breakpoint line for such a
function-breakpoint
is not at the correct line after some editing. It is corrected after
each
start of the debugger to the correct line).

Oh, it is very simple to write your wishes, but very hard to realize :-)

BTW: I have also some other "simple tasks" which I would have in RHIDE,
but ...

At least I see no way for doing this. But if someone else has an idea,
I will try my best if it is an idea which can be implemented.
