Is there a shortcut key to bring up the call hierarchy of a method inline with the code, in the quick menu format, rather than bringing up the call hierarchy panel?
To be complete: for the Mac user
Press command + alt + F7
Don't forget you can always do the action name search with Command + Shift + A and search for "call", amongst other commands.
I don't think the inline method call hierarchy exists (please enlighten me if I am wrong).
If you just want to jump to one of the callers of the method, CTRL + ALT + F7 is the way to go. On a Mac, use: Command + Option + F7
There is a 'Default Keymap Reference' on the 'Help' menu
Type hierarchy can be also useful sometimes (shows the parent and child classes of the current class):
Press Ctrl+H
