some I use
# suffix aliases
alias -s {epub,pdf}='mupdf-gl'
alias -s svg='inkscape'
alias -s {mp4,mpg,mov,avi}='mpv'
alias -s {png,jpeg,jpg}='feh --action1 "rm -v %F"'
alias -s {doc,docx,odt,xls,xlsx,ppt,ods}='libreoffice'
basically it allows me to type only the name of the file and it opens it with the right app
