I just do `yay -Syu` every week or so. What does `-Qtd` do?

Same, also the ocassional paccache (https://wiki.archlinux.org/title/Pacman#Cleaning_the_package...). I think -Qtd list orphaned packages.

Of course all's in the wiki, some useful links:

From [0]:

> To list all packages no longer required as dependencies (orphans):

    $ pacman -Qdt

That just lists them, how do you remove them?

`sudo pacman -R $(pacman -Qtd | awk '{print $1}')` ?

`pacman -Qtdq` will list the package names

`pacman -R -` will read names from stdin
