Fly/walk camera mode (shift+F) will not work in pose mode, or at least the hotkey doesn’t.
I can get into walk/fly camera via the view>navigation>walk/fly cam and it works, but again, the hotkey for it in pose mode does not work.
No idea how to submit bugs so if someone could direct me that would be great!
For now, what do I look up to change the hotkey? Perhaps changing it from shift+F will make it work for now until they fix it in 2.74.
In Pose mode if you select a bone for example Hand.L and press Shift+F then it automatically selects the flipped bone Hand.R, so I think it’s not a bug.
https://developer.blender.org/ . Also via the Help menu in Blender. You have to create account/log in to submit a report.
This is not a bug. It is poor documentation. In userprefs/input set the search filter to Key-binding and type shift f into the search box to see all the other places where the global shortcut for Fly is trumped (sculpt mode, weightpaint mode, etc). You can still fly but you have to use the menu or change/disable the overriding shortcut.
