I want to develop a IntelliJ/Idea plugin that allows the following: When I Ctrl+click on a literal int, say 1234, I want to navigate to the method method_1234 if that exists in the current class.
What IntelliJ-"action group" do I add my new action into? From the tutorial for the plugin SDK I watched it seems that it is semantically important in which group I add my new action? Or am I wrong? Is only the code in the plugin important and the group is only where in the menus (or elsewhere) my new action appears?
Action group is semantically unimportant, it only determines in which menu your action will be visible to the user. For Ctrl+Click action, it seems to make no sense to show it in menu at all, so you can create an action without any group.
