What does 'Clear Origin' (AltO) do? Someone mentioned it on our general chat.

  • $\begingroup$ It does different things, it depends on the mode (clear origin in object mode, toggle proportional editing connected/disabled in edit mode). $\endgroup$ – CodeManX Feb 22 '15 at 13:36

Select a child object of a parent, and press AltO (that is the letter O). It will move the child to the parent, while still keeping the parent relationship intact. The name Blender uses is "clear its origin".

AltO is ambiguous as it performs a different action depending on which view area you are in. In the 3d view, you can use it to clear the object origin, in the text editor, use it to open a text block, in the sequencer it clears strip offsets etc.

To see the full list, search by Key-Binding for Alt O under Input in user preferences.
