If you compile your own Linux kernels very often like me, you might appreciate this tip:
When searching for an option with `/`, you can jump over to where it's defined by just pressing the number next to it.
Let's say I searched for `wireguard`. This is what will pop up:
Symbol: WIREGUARD [=m]
Type : tristate
Defined at drivers/net/Kconfig:74
Prompt: WireGuard secure network tunnel
Depends on: NETDEVICES [=y] && NET_CORE [=y] && NET [=y] && <...snip...>
Location:
-> Device Drivers
-> Network device support (NETDEVICES [=y])
(1) -> Network core driver support (NET_CORE [=y])
Selects: NET_UDP_TUNNEL [=m] && DST_CACHE [=y] && CRYPTO [=y] && <...snip...>
Symbol: WIREGUARD_DEBUG [=n]
Type : bool
Defined at drivers/net/Kconfig:106
Prompt: Debugging checks and verbose messages
Depends on: NETDEVICES [=y] && NET_CORE [=y] && WIREGUARD [=m]
Location:
-> Device Drivers
-> Network device support (NETDEVICES [=y])
-> Network core driver support (NET_CORE [=y])
(2) -> WireGuard secure network tunnel (WIREGUARD [=m])
In the output above, the numbers next to the lines `Network core driver support` and `WireGuard secure network tunnel` are hotkeys, and if you press `1` or `2` in this page, you will jump to that option.
I've probably messed around with Linux kernel configuration for 2-3 years now, and I just today found out about this, by accident. I am now sad about all the seconds wasted trying to find something nested very deep...
