I wanna use text editor for my kernel configuration because I found menuconfig (ppseudo-graphical) very unconvenient. How can I do that?

caputmanus,

When you use a text editor to configure the kernel you usually end up with an illegal configuration that builds a broken kernel, or if you are lucky, fails to build.
The kernel .config settings are not independent.
The configure tools know this and take it into account as you work.

There are two issues ...
Some things depend on other things already being selected. They will be hidden if the Depends On: is not true.
Some things force other options on too. You will get that wrong with a text editor.

To search hidden options in menuconfig, press the 'z' key. This toggles the display of hidden options.
Now you can go to them and read the help, They still cannot be selected, until you make the Depends On: true.

The closest you can get to a text editor is

Also, there is / for search. It also displays entries which are hidden and its dependencies.

Our handbook https://wiki.gentoo.org/wiki/Handbook:AMD64/Installation/Kernel lists a newer command to configure the kernel options make nconfig, but the older make menucofig is sitll available and maybe more pleasing.
