[Grammar] Fix/Fixing/Fixed a typo

[kadioguy]

I have seen the three styles of writing:

a. Reason for Editing: Fix a typo
b. Reason for Editing: Fixing a typo
c. Reason for Editing: Fixed a typo

Grammatically, I assume that (a) is a verb phrase, (b) is a gerund phrase and (c) is a verb (in the past simple) phrase.

But what is the difference in meaning among them (especially between a. and b.)?

I think, logically, "reason for editing" requires a noun phrase, which (b) (gerund) is while (a) and (c) are not.

Thank you, tedmc.

As for meaning, I think (c) means the typo has been fixed (the writer fixed a typo). If so, what do (a) and (b) mean? What is the difference in meaning between them?

Any reply is welcome.

Ignoring the grammatical requirement for a gerund (which I accept), I would say that a) is a shortened form of "I was here to fix a typo" and b) is a shortened form of "I was here fixing a typo".
