This is more in the "hack" category, but here is a solution for bookmarking directories[1] that I am quite fond of:

mkdir -p ~/.marks/
export CDPATH=.:~/.marks/
function mark { ln -sr "$(pwd)" ~/.marks/"$1"; }

# This file contains pin mappings for the Creality "v4.2.7" board. To
# use this config, during "make menuconfig" select the STM32F103 with
# a "28KiB bootloader" and serial (on USART1 PA10/PA9) communication.

# If you prefer a direct serial connection, in "make menuconfig"
# select "Enable extra low-level configuration options" and select
# serial (on USART3 PB11/PB10), which is broken out on the 10 pin IDC
# cable used for the LCD module as follows:
# 3: Tx, 4: Rx, 9: GND, 10: VCC
