macosmenu bar
Clicking on the Wifi icon in the menu bar while pressing and holding the option key presents the user with a different and detailed view. The option-key is a nice feature. It works on a lot of the menu bar icons as well (sound and bluetooth).
I'd be nice if I could set this feature as the default action when interacting with those menu bar items.
How can I set this to be the default action on El Capitan?
If a menu icon is allowed to move, command + mouse select will work.
You might have to patch the program (or System Ui Server). Have you asked the developer if they can implement this as a feature?
Only the Apple icons are movable on my 10.6.7 systems so it certainly isn't easy for a developer to get this working and may be impossible in practice.
The only workaround would be to have a script that delays the radium start as the leftmost item is the last to load. If you had a launch script that slept for 3 minutes and then killed, relaunched that app - it would be leftmost until another started... If it was really important, you could kill and relaunch it periodically every X minutes to ensure that over time it's the leftmost icon without you taking manual action.
I have been using this for a while and it seems to be configurable to do what you need.

Until now I've only found a workaround:
Install BetterTouchTool and create a special trackpad gesture or mouse gesture to invoke an option+click. In the example below I use the trackpad and a 3 finger double-tap in Global to do that:
From now on a 3 finger double-tap on the Wi-Fi menulet (and other menulets) will reveal the advanced or detailed view.
