There are 2 arrow keys in the left upper corner of the IDE. I thought they would serve as a history of visited places. But they behave really strange.
Is this a weakness of the IDE or didn’t I get its purpose right?
You are correct, and in fact there have probably been a dozen or more threads with several thousand comments on this topic. 
And why doesn’t the Xojo team solve the problem?
Because there are bigger problems to solve 
No but really, nobody has any idea how they work.
