In PyCharm, how to go back to last location?

Under ArchLinux with PyCharm CE 3.1 works the combination Ctrl + Alt + Left.

This is the way I find out the combination:

1. (Right click) Go To -> Implementation(s)

2. Double Shift -> Back

   

3. There is an option Back in the section Actions

4. Ctrl + Shift + A

   

5. And then the cursor comes back

All in all, it has nothing with PyCharm;

In my case, there was a global key combo of another program, that masked Ctrl-Alt-Left

I solve it by remapping "file > settings > keymap > main menu > navigate > back".

I chose Alt+Left, which intuitively feels likes web browsers "back" behavior.
