how can you view all keystrokes on a word processor?

I may have difficulty posing this question, if so, please try to read my mind..;-)

I am forced to use Google Docs to type and print documents.

While doing so trying to type a document I needed to see the

invisible spacing between certain letters and words.

I was trying to type, what is for me, a booklet of 3 pages which required

I place words in different areas of each page.

Some time back, when using a Microsoft word processor I was shown

how to click SOMETHING or other which would make all my keystrokes

visible....the spacing between words, etc.

Is that a function of all computer word processing programs?

And if I'm making sense, can I do it with Google Docs?

Thanks one and all
