Stuck in free-rotation in scene mode?

I'm not entirely sure what I did, but I must have pressed a number of keys by accident when sitting down to work on my project today, and for whatever reason, Unity refuses to focus on an object in the scene window, now... When I select an object and press "f," it does its normal animation dealie where it moves the camera to the corresponding position and rotation, as per usual. The trouble is, once that's done, it still won't rotate the camera around that point, but in stead rotates it about the center-point of the scene camera (or what I assume is its center-point).

I looked all through the preferences and have gone through several searches to find some sort of "free rotation" hotkey for the scene view, but have had no luck, thus far. Forgive me if this seems like a "noobish" problem, but clearly this isn't documented well enough for me to have any way of knowing what to do in this situation...

Does anyone know what I may have done, and/or how to fix it??

 

I will do this but once, and then I'm thinking I'll just post it in the unity answers section... since apparently people don't check out new threads all too often, here...

 

Yes, I'm aware of the f-key dealie, and I tried hitting z, and switching between global and local, as well as center and pivot. It actually went away, for a time, but just recently came back. I'm thinking this might be a bug, since this time I'm almost certain I didn't press any random keys.

[edit] Figured it out. I don't know what the hotkey is, but if you right click the center box on the axis icon in the upper right part of the scene menu, you'll get a dropdown menu. I was in perspective mode, apparently.

 

for me it was the little lock icon next to the axis - was locked.. now unlocked and back to normal.. perspective mode is correct mode

+1 small victory today
