How would I make a conditional branch with RGSS?

[Untra]

I'm working on making a program that will make the screen flash every time I press a key on the keyboard. The only problem is I need to utilize almost every single key, and the normal RTP has input for only sixteen or so keys. My question is: Using what script, how would I be able to make the game check to see if each button is pressed, and utilize that to make a conditional branch?

Thats currently what the event looks like. I would like to make it so that the event will
A.) Check to make sure the button is pressed
B.) Display the necessary image/s
C.) Wait a frame
D.) Check to see if the button is still being held down (pressed)
Ea.) If so, go back to C.
Eb.) If not, erase the image

I would to know how I would be able to do this with scripts, as so that I can utilize the entire keyboard. Can I do that?

Edit: This may need to be moved into a different forum. My bad if so.

Use the custom Input module I made.  In addition, add the following to a new script section (after the
custom module but before the last one in the script editor):

def anyKeyTriggered?
  for i in 0...256
    next if i<8 && i!=3
    return true if Input.triggerex?(i)
  end
  return false
end

It can be used in a Conditional Branch event command like this:

anyKeyTriggered?

EDIT:  After looking at what you're trying to do, the approach can be done differently (still using my custom Input module).  Replace "The Right button is being pressed" in your example with, for example, "Input.pressex?(0x52)" to check whether the R key (not R button) was pressed.

This helps, as it allows for more keys, but I need a way to utilize almost every single key on the keyboard.
I need these keys specifically:
` 1 2 3 4 5 6 7 8 9 0 - = {Backspace}
{Tab} q w e r t y u i o p [ ] \
{Caps Lock} a s d f g h j k l ; ' {enter}
{lShift} z x c v b n m , . / {rShift}
{UP} {DOWN} {LEFT} {RIGHT}

The number used in Input.pressex does allow for every key, even mouse buttons.  That number is a virtual-key code, for example, 0x52 is the virtual key code for the R key. I will reproduce the document on MSDN explaining virtual-key codes (only the relevant parts will be reproduced)

The following table shows the symbolic constant names, hexadecimal values, and 
keyboard equivalents for the virtual-key codes used by the Microsoft Windows 
operating system. The codes are listed in numeric order.

Haha! Thats what I needed to know!
I took a look at the script and it had a few functions listed there for the normal RTP keys, but this certainly does work as the full keyboard! I might even be able to create a side event that will allow for the change in hue of the flashing colors via means of the mouse wheel. Awesome!
Topic is resolved. And bookmarked.
