How to solve copy-paste issue in VIM (especially Arch Linux/Manjaro Linux)

1- Install gvim (it'll invoke the normal anyway, not the GTK version)
2- Put set clipboard=unnamed in your $HOME/.vimrc

3- Save and test it out. Now you can happily use your mouse

(Otherwise, we will need to use the Shift press button whenever we want to copy and paste.. which is troublesome - at least for me!!!)

Now problem solved. Thanks
