HELP DESK FOR NEWBIES

Okay, this is something that has really bugged me, and I've asked for help, but I still can't figure it out all the way. Now....
In RMXP, how the heck do you set certain buttons to do certain actions, like making SHIFT jump, for example? That is what I want to do, but I can't make it work!
By the way, the advice was that I had to use variables and parallel processes, and that shit=11. ??? What does that mean? ???

1> is it possible to make a picture hover over your map and not move? such as always having a Sun picture in the top right corner that I can change as time passes.

2> how do I make my message boxes a> smaller b> transparent?

3> how do I make it so that when I press a key, I can tell the game what to do? Such as Quiversee's jumping, or pressing a different key to bring up a "quick menu".

Also, does anyone know of any cool "tricks" tutorial pages that might include how to do these and other stuff?

1) In the Show picture command, make sure "Scrolls with map" is unchecked.

2) Go to the Battle layout tab in the database. Pick Alternative -> Small window -> Transparent. I believe the Classic one can let you do Small window too, but not transparent.

3) Make a parallel process event (It could be a common event if you want it to apply in every map). Have a Key input process command, make sure "Wait until key press" is checked, and check off the keys that you want it to check. Within the key input process command, make sure you set it to a variable that you aren't already using. Take a look at the numbers to the right of the keys. It'll show 1-4 for the arrow keys, 5 for enter, 6 for escape, and so on.

Then, after that key input process command, make a Conditional branch. Compare the variable to the number to the right of the keys. So, if you want to check to see if the Escape key was pressed, the variable must equal 6.

Then, do whatever you want to happen within that Conditional branch.

I don't feel like checking this up for RMXP, but it should be similar.
