I really like the greyed out area in the teminal whereby you can type over the "sudo pacman -S" in order to alleviate incorrect requests.
Is it possible to have a keyboard shortcut that automatically inserts this without typing. Or is it already available to use. I could not find anything relating to this.
Cheers.
Just use -> arrow key or press tab
Many thanks. Thought there would be a way. 
I tried that but it did not appear to work.
Ctrl+F is probably what you are looking for 
Thank you. Will try that.
Just set up an alias:
alias u="sudo pacman -Syyu"
type u press enter.
thanks. I have carried out what you suggested without anything changing. Where do you type u and press enter. I tried where you would normally enter “sudo pacman -S” without success.
Am I missing something. If so, what.
Cheers.
-Syyu is considered bad practice since it puts extra unneccessary load at the servers, use -Syu instead.
Setting up an alias is easy.
Open ~/.zshrc, find the lines containing alias=, add your own alias as described above.
Then reopen the terminal or type source ~/.zshrc to apply the alias. Its enough to type u in the terminal to update now.
Thanks for the explanation. Will use -Syu only in future.
