i also have the chmod one, but mine is named just x:
alias x='chmod +x'
I also have the yt-dlp "$(wl-paste)" one, but its build around a custom script. So sharing it here makes no sense. Its funny how often we do same thing in different ways (extracting or creating archives in example). Often aliases get development into function and then they turn into scripts. For some of the more simple aliases, here a selection:
alias f='fastfetch -l none'
alias vim='nvim'
alias baloo='balooctl6'
