I am trying to find a keyboard shortcut that would allow me to open an Xcode popup with current problems. Here is a screenshot that shows what I mean:
Click ⌘+ 4. It will lead to the left menu a list of current problems.
This is not a popup, but it does list problems. I don’t think there is a shortcut for what you want. The following is a list of all the shortcuts associated with the problem:
Question
⌘ 4
Show problems
Ctrl 7
Go to the next release
⌘ '
Go and fix the next release
Ctrl ⌘ '
Go to previous release
⌘ "
Go and fix the previous release
Ctrl ⌘ "
Ctrl ⌘ M
