we need 3 verbs and 1 variable and 2 macros with the same key.
these are the macro verbs.
i have custom interface so i use the macro maker.
you just use the "key up" feature for in this case, c2().
make another macro.
just a regular one with the same key that uses c1().
this is the block verb.
when the key is up, its disables the variable thus, disabling the block. make sure to call the block verb in the macro verbs!
when the key is pressed, blocking is not 0 so dm calls upon the "else" function. it tells dm to start blocking. this is your key hold system!.
it acts a a key sensor.
i thought of this myself. feel free to use it.
if anything, reply to the post please.
