There are already several shortcuts/actions to jump to/between EnterMethod and LeaveMethod log entries. If a LeaveMethod log entry is selected, you can jump to the related EnterMethod log entry with “View | Jump to Matching Entry” (Shift+Ctrl+M). When you are inside a method, you can jump to the start with “View | Jump to Method Start” (Shift+Ctrl+S) and to the end with “View | Jump to Method End” (Shift+Ctrl+E).
The ‘-’ and ‘*’ actions are built-in features of the used tree control, so I’m not sure if we can easily extend this. However, I will look into it and added it to the feature request list. Thanks for the suggestion!
