I use Eclipse for Python development and depend on the F2 function key to send lines of code to the console. Recently, F2 has stopped working in my installation of Eclipse Neon. I have tried everything I can think of to get it to work again:

close and reopen the python module
close and reopen Eclipse (as recommended on Stackoverflow)
check the key bindings to make sure F2 is properly bound, unbind it, rebind it, reset to default key bindings
reboot my computer
install new version of Eclipse, Oxygen, twice..

In one of the newly installed Oxygens, at least the first time I press F2, it does open the pop-up asking what console to start with, but then after the console is open it does nothing. 
In the Neon installation and the other Oxygen installation, F2 just does nothing, not even open a new console when none is active.
Would you have any idea I can try to get F2 back to work?
I have gotten it back to work, by uninstalling pydev 6.3 and re-installing pydev 6.1. I'm not sure why this works as I was working in 6.2 when the issue first arose. I tried to solve it by upgrading to 6.3, but that didn't work. For some reason, downgrading back to 6.1 now makes it work again.
