make menuconfig allows hidden options to be displayed. The 'z' key toggles the feature on and off. It works everywhere that 'z' is not a shortcut.

- I mentioned using "z" already in my other article: "Manual_kernel_configuration" ... as a quote from your forums-post ;-)
- But this is not true: "With hidden symbols displayed, they also appear in search results". I searched several times for an hidden option and it was found by / EVEN if "z" was not toggled on. / will find always an option if option exists - independent of hidden or not. You need "z" only to be able to go into <Help> of an hidden option; not to find it.
