Key count not correctly measured

Hi,
The key count is incorrect measured when holding the alt button.

System:
Current version is 2.8.1.
Windows 10 x64

How to reproduce?
have the geek window open to see the issue.
Hold the left alt button and press the arrow left and right.(10 times)
You will see that only the alt press is measured.
Why would you hold the alt button? well is a fast way of jumping in your code ;-)

regards,
