Many users have shared techniques for improving command retrieval in terminal environments. One effective method is to append "###" to frequently used commands for easier identification during searches. Additionally, users recommend adding comments to commands, such as `yay - Sc # clear pacman and yay caches`, to enhance future retrievability. This approach allows for easier navigation through command history using search shortcuts like Ctrl-R. Some users prefer using text over icons since it expedites the search process and increases efficiency compared to sifting through icon selections.
