问题 I am running Python 2.7.3 on a Ubuntu 12.04 LTS distribution. I use spyder 2.9.1 as IDE. As detailed in another Stackoverflow post of mine, I upgraded matplotlib from 1.1 to 1.5.1 only to find that there are acknowledged clashes between the IDE and matplotlib 1.5.1.

问题 I believe there is a shortcut in Spyder to open the current object (i.e. the object where the flashing text cursor is) in the Object Inspector.
