Can I export a file from this commit in Mercurial?

Question

Let's say I have a file main.cthat I encoded. I already made # 100, but unfortunately I found that I need to restore some functions that I encoded to commit # 50. I know that I can use the repository explorer to see the differences between the different versions in this file, but what I would like to see is the file itself, since it was included in commit # 50 (without all these + and - the file, as it was at that time).

Is it possible?

I would not want to commit to # 50 to get these functions and then go back to # 100.

thank

hg update -r 50 that_file
