After some more thinking I am not sure if this is the best approach.

1. After clicking mouse-1 in buffer `*Metahelp*’ you can easily search in this buffer but
all the mapped keys doesn’t work at this point. You need to look for what you need in the buffer
and run C-h ? once again.

2. Author of the bug highlighted that the current behaviour is not friendly. I am also not sure
if adding another key just for changing the window is a good solution.

At this point I do not know how we should handle this case.
