Avoid typing long filenames in terminal, shortcut for selecting files?

You probably know the answer to this, because I know it exists.

I have super long filenames with md5 hashes and I sucks to type the whole hash in the console. Because... just because

What is the shortcut for selecting a file in the current directory? Like you get a sort of loop through the filenames from which I can chose a file.

thanks in advance

You probably just start to type the first few letters and hit TAB once or twice. Is this what you mean?
