Projects General Guidance

Hi! I'm Daniel from Spain, my English is not so good but i will try to explain you my doubt.
I'm working in a project using Arduino UNO (because i'm bound to use it) as KeyBoard.
In this moment, I only have to use a PUSH BUTTON as a RIGHT BUTTON of my MOUSSE,
but i don´t know if i can use the library ----UsbKeyboard.h---- or any one similar.

I'm lost in this and any help would be great for your move because i don´t know how continue my project.

Thank you so much,

I hope you can understand me...

What keyboard? What buttons? Can you show your circuit?

In this moment, I have only one button that have to
connect with the PC as an ENTER BUTTON.

Here is a picture to try to explain my project.
Thank you everybody.
