If you are logging in in multiple *nix systems I suggest you keep the Ctrl+l.
I started to notice that the more I adopt in terminal specific commands to MacOS the hard is to be productive while I login to various systems.
I want also to force myself (but did not do it yet) to use a simpler Vim configuration. Maybe just line numbers so that when I login into a new system I should not need any plugin or any other shortcuts. Still I like my .vimrc file but I plan to do this in near future.
